If & angle; A and & angle; B are supplementary and & angle; A = 4x-8 and & angle; B = 2x + 2, what is the value of x?

A) 31

B) 180

C) 43

D) 22

Supplementary angles are angles which add up to 180. To solve this, add the values of both angles and set it equal to 180, (4x-8) + (2x+2) = 180. First, combine like terms, 6x-6=180. Now, solve for x, add 6 from both sides, 6x=186, divide by 6, x=186/6=31. This makes x equal to 31, making your answer A.
