Answer:

I don't know the exact answer but I that x=5

Step-by-step explanation:

12/3=20/x

12x=20*3

12x=60

<h2>Answer:</h2>

We will create a proportional relationship to find x.

$\frac{12}{3} = \frac{20}{x}\\\\12x = 60\\\\x = 5$

The missing side is <em>D. x = 5</em>.

How to solve this? Don't just give me the answer help me learn this.

Sphinxa [80]

Answer:

I'm not entirely sure but I think that what is says is that it wants you to find the value of x in (4x+28) to make it 116 degrees because it is that same angle. So what you do is you get (4x+28)=116 and you do this because they are the same angle so you use 116 and get it to solve x. Since I'm lazy, then I go to this website and type the equation in: m a t h w a y . c o m but without all of the spaces, I had to do that so it would let me answer this, but I'll do it the real way this time. (4x+28)=116 Their is a rule in math that as long as you do something to one side of the equal sign in the equation, you have to do it to the other and it will still work. So, you minus 28 from both sides so that you can get rid of it and you now have 4x=88. Now you should know this part but you divide 4 from both sides to make so x is alone. Now you have x=22 because you divided 4 from each side. So their is your answer: x=22.

Step-by-step explanation: If you have the answer key that you can check from to make sure you got it right because I know some teachers let you do that, then you should make sure that is right, but I am pretty sure it is.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

Lapatulllka [165]

Hello!

The formula for the area of a sector can be written as follows:

Area = $\frac{1}{2}$ $r^{2}$ (R)

In the above formula, “r” represents the radius while “R” represents the radian measure of a sector. The radius is given to us in the image above as 10 inches. However, we still need the radian measure of the two sectors. To find this measure, we can use the following conversion:

1 degree = $\frac{pi}{180}$ radians

Because the two sectors have a given measure of 72 degrees, we need to multiply both sides of the above conversion by 72:

72 degrees = $\frac{72pi}{180}$

Reduce the fraction on the right side of the equation:

72 degrees = $\frac{2pi}{5}$

We now have the radian measure of both sectors. Now simply insert this and any other known values into the “area of a sector” formula above:

Area = $\frac{1}{2}$ $10^{2}$ ( $\frac{2pi}{5}$ )

Simplify the right side of the equation to get the following answer:

Area = 20 pi

We have now proven that the area of one sector is equal to 20 pi.

If, however, you need the combined area of the two identical sectors, simply multiply the proven area by 2 to get a total area of 40 pi.

I hope this helps!
