<u>**Answer:**</u>

**5x = 100°**

**4x = 80°**

<u>**Step-by-step explanation:**</u>

We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.

We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.

So we can write it as:

Finding the measure of both the angles:

**100°**

**80°**

**Answer: i believe its a x=2**

10 + 8c= 42

subtract 10 from both sides

8c= 32

divide both sides by 8

c= 4

CHECK

10 + 8(4)= 42

10 + 32= 42

42= 42

ANSWER: c= 4

Hope this helps! :)

The mad is 9

the mean is 4.5

then calculate all differences and you get 9
