Can you still use the triangle sum Theorem even if a triangle is not in 180 degrees?
Answers
Hi!
You cannot.
This is because ALL triangles MUST have 180 degrees, so if it doesn't it's not even a triangle. Therefore you cannot use it because, well, it's not a triangle.
Answer:
The sum of interior angles is 180 degrees (Triangle Angle Sum Theorem). All interior angles of a triangle are more than 0° but less than 180°.

An acute angle of a right triangle measures 30°, and the length of the triangle's hypotenuse is 10 ft. Find the missing angle measure and side lengths.
Answers
Answer:
missing angle <60 and side lengths 5, 5\(\sqrt{3}\)
Step-by-step explanation:
we understand from the given information that the triangle in question is a special right triangle
and since this is a special triangle the side lengths follows :
the side length that sees <90 is represented by 2x
the side length that sees <60 is represented by x\(\sqrt{3}\)
and the side length that sees <30 is represented by x
2x = 10 so x = 5 and x\(\sqrt{3}\) = 5\(\sqrt{3}\)

Answer:
x = 11
z = 86
Step-by-step explanation:
8x + 6 and 10x-16 are vertical angles
Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.
To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:
8x + 6 - 6 = 10x - 16 - 6
8x = 10x - 22
Now we can subtract 8x from both sides of the equation:
8x - 8x = 10x - 22 - 8x
0 = 2x - 22
To solve for x, we can add 22 to both sides of the equation:
0 + 22 = 2x - 22 + 22
22 = 2x
Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2
x = 11
Therefore, the solution to the equation is x = 11.
Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)
Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.
First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94
180 - 94 = z
z = 86
m-2n = 8
n = m - 2
The value of m in the system of equations is:
Answers
Step 1: Substitute information
To solve this we will use the substitution method. This means that we will use the information provided to us in the second equation, and substitute it into the first equation. We are told what n equals, so let’s substitute this now.
m-2n=8
m-2(m-2)=8
Step 2: Distribute
Now that we have substituted the information, let’s distribute. This means that we will multiply the numbers on the outside of the parentheses with the numbers on the inside of the parentheses. Let’s do this now.
m-2(m-2)=8
m-2m+4=8
Step 3: Combine like terms
Now that we have distributed, we can continue solving the problem. The next step is to combine like terms. This means to combine terms with the same variable, or lack of. In this case, that is m and -2m.
m-2m+4=8
-m+4=8
Step 4: Get variable alone on the left side
We can now work to get the variable alone on the left side. We can do this by moving the number on the right side, in this case by adding 4 on both sides.
-m+4=8
-m=4
Step 5: Make m positive
In this final step, we must work to make m positive. We can do this by multiplying each term by -1. This will make m positive, and 4 negative. Let’s do this now.
-m=4
-1(-m)= -1(4)
m= -4
This is your answer! M is equal to -4. Hope this helps! Comment below for more questions.

mailbox company produced decorative mailboxes. the company's average cost per unit is $19 when it produced 851 mailboxes. mailbox company has $10,069 in fixed costs. what is variable cost per unit?
Answers
The variable cost per unit for the Mailbox Company is $7.17.
How to calculate the variable cost per unitIn order to calculate the variable cost per unit for the Mailbox Company, we can use the following formula:
Variable cost per unit = (Total cost - Fixed cost) / Total units produce
To use this formula, we first need to calculate the total cost of producing 851 mailboxes.
We know that the average cost per unit is $19, so the total cost would be:
Total cost = Average cost per unit * Total units produced
Total cost = $19 * 851
Total cost = $16,169
Now that we know the total cost, we can use the formula to calculate the variable cost per unit:
Variable cost per unit = (Total cost - Fixed cost) / Total units produced
Variable cost per unit = ($16,169 - $10,069) / 851
Variable cost per unit = $6,100 / 851
Variable cost per unit = $7.17

problem 4. if a is a skew symmetric n xn matrix such that n is an odd number, evaluate det(a).
Answers
The determinant of the transpose of A is equal to the determinant of A. And since the transpose of a skew-symmetric matrix is its negative, this implies that the determinant of A should also be equal to its negation. The only possible value that satisfies this condition is zero. Therefore, det(A) = 0 when "n" is an odd number.
We can use the property of skew-symmetric matrices, which states that the determinant of a skew-symmetric matrix of odd order is always 0. This means that for the given matrix A, which is skew-symmetric and of order n, where n is odd, det(A) = 0. In order to prove this property, we can use the fact that the determinant of a matrix is equal to the product of its eigenvalues. Since A is skew-symmetric, all its eigenvalues are imaginary and come in pairs of the form λ and -λ. Since n is odd, there is at least one eigenvalue that is equal to 0, and therefore det(A) = 0. The answer to problem 4 is that the determinant of the skew-symmetric n x n matrix A, where n is an odd number, is equal to 0.
When dealing with a skew-symmetric matrix "A" of odd order "n" (n x n matrix), the determinant of A is always zero.
In a skew-symmetric matrix, the elements below the main diagonal are the negation of the elements above the main diagonal, and the elements on the main diagonal are zero. Mathematically, this can be represented as A(i,j) = -A(j,i) for all i and j. Since "n" is an odd number, multiplying an odd number of negative pairs will result in a negative value for the determinant.

Answers
If a stock has been declining in price at a steady pace of $ 2.59 per wee If the stock started at a price of $ 618.50 per share then the number of weeks it will take to reach $ 11.00 is 235 weeks.
The initial price of a stock is = $ 618.50
The rate of decline of the price of stock is = $ 2.59 per week.
Let after T weeks the price of stock will be $ 11.00.
The suitable equation for the condition will be:
618.50 - 2.59T = 11.00
2.59T = 618.50 - 11.00
2.59T = 607.50
T = 607.50/2.59
T = 234.56
So approximate to nearest week we get, T = 235 weeks.
Hence number of weeks it will take to reach $ 11.00 is 235 weeks.

Answers
the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).
n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).
To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.
Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.
Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.
Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

Hi there!
We are given the following quadratic equation:
2x²-3x-5=0
And we want to solve it.
There are multiple ways to solve it, but we can solve this by factoring.
One way to factor an equation like this if the leading coefficient a (the coefficient in front of x²) is greater than one, is to multiply the coefficients a and c (the coefficient without any variable on it) together, find out which numbers multiply to ac and equal b (the coefficient in front of x (without any exponent)), and then factor the equation as (ax+n)(ax+m)=0, then solve for x, where m and n are the numbers that multiply to ac and equal b
To start, multiply 2 and -5 together (a is 2 and c is -5):
-10
Now find out which numbers multiply to -10 but equal -3 (-3 is b):
Those two numbers are -5 and 2
Now factor the equation like this:
(2x-5)(2x+2)=0
Now solve for x:
2x-5=0
Add 5 to both sides
2x=5
Divide both sides by 2
x=\(\frac{5}{2}\)
2x+2=0
Subtract 2 from both sides
2x=-2
Divide both sides by 2
x=-1
So the answers are \(x=\frac{5}{2}, x=-1\)

Find the function y whose derivative x is 0 dy is 7.x² +8.x-2 and y has a value of 1 when dx
Answers
The function y whose derivative is dy/dx = 7x² + 8x - 2 and has a value of 1 when x = 0 is y = (7/3)x³ + 4x² - 2x + 1.
To find the function y given its derivative and an initial condition, we can integrate the derivative with respect to x.
Given that dy/dx = 7x² + 8x - 2 and y(0) = 1, we can integrate the derivative to find y(x).
Integrating both sides of the equation with respect to x, we have:
∫ dy/dx dx = ∫ (7x² + 8x - 2) dx.
Integrating each term separately:
∫ dy/dx dx = ∫ 7x² dx + ∫ 8x dx - ∫ 2 dx.
Integrating the terms, we get:
y = (7/3)x³ + 4x² - 2x + C,
where C is the constant of integration.
Using the initial condition y(0) = 1, we can substitute x = 0 and y = 1 into the equation to solve for C:
1 = (7/3)(0)³ + 4(0)² - 2(0) + C,
1 = C.
Therefore, the function y is:
y = (7/3)x³ + 4x² - 2x + 1.
Thus, the function y whose derivative is dy/dx = 7x² + 8x - 2 and has a value of 1 when x = 0 is y = (7/3)x³ + 4x² - 2x + 1.

Show all work
Answers
Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.
Here are the steps on how to calculate the amount Henry invested:
Convert the annual interest rate to a monthly rate.
\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)
Calculate the number of years.
\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)
Use the compound interest formula to calculate the amount Henry invested.
\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)
where:
FV is the future value ($75,000)
PV is the present value (unknown)
r is the interest rate (0.375%)
t is the number of years (1.5 years)
\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)
\$75,000 = PV * 1.0297
\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)
PV = \$72,831.68
Therefore, Henry invested \$72,831.68 in the savings account.
