Question

Solve for X, please write an explanation.

Answer 1

Explanation:

2x+20 and 2x-4 are supplementary angles...they form a straight line and thus = 180 degrees when added together

2x+20 + 2x-4 = 180 simplify

4x + 16 = 180 subtract 16 from both sides

4x = 164 divide both sides by 4

x = 41 degrees
