Answer:

B) 5(x+6)=55

Step-by-step explanation:

Complementary angles add up to 90 degrees.

Let x = complement of angle M is 10 degrees.

We want to solve x + M = 90.

Let's solve for M.

10 + M = 90

M = 90 - 10

M = 80.

The measure of angle M is 80 degrees.

Answer:

An example of scale factoring that could be used in everyday life is when modeling. When modeling and object you don't make it, for example, 10 feet because that cannot fit on a computer screen. So when on a computer you see a much smaller-scale version.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Answer:

See picture attached

Step-by-step explanation:

The missing question is:

Draw the graph of the growth function by plotting its G-intercept and another point.

Given the function:

G(x) = 2 + 7x

its G-intercept is found when variable x is equal to zero.

G(0) = 2 + 7(0) = 2

Then, the G-intercept is point (0, 2)

To graph a line, two points are needed. Replacing x = 1 into the equation, we get:

G(1) = 2 + 7(1) = 9

So, point (1, 9) is on the line. The graph of the function is the line that passes through these two points, as can be seen in the picture attached.

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅

Step-by-step explanation:

if we write out the entire expression we have:

0.5n - 0.3 - 0.8n + 0.9 (two negative signs create a positive sign)

then we add and subtract

and receive

-0.3n + 0.6

Answer:

-0.3n + 0.6

Step-by-step explanation:

We can eliminate the parentheses, obtaining:

0.5n - 0.3 - 0.8n + 0.9

and then combine like terms, obtaining:

-0.3n + 0.6

explanation:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Since you already have y isolated in one equation, you can plug it in and use it in the other equation2y = 8x + 122(4x + 6) = 8x + 128x + 12 = 8x + 12Get the x's to one side 12 = 12Meaning you have infinitely many solutions. Try plugging in any x value you can think of and the left side will always equal the right side. sox = 0 --> 8(0) + 12 = 8(0) + 1212 =12x = 1 --> 8(1) + 12 = 8(1) + 1220 = 20and so on.I graphed it here for you and the 2 functions are on top of each other which means at every x value y = 4x + 6 is equal to 2y = 8x + 12
