Question

The angles below are supplementary. What is the value of x?

A pair of supplementary angles is shown. One angle measures 7x + 33, and the other angle measures 70.

5.3
8.14
11
14.7

Answer 1

It would be 11.

Supplementary angles are two angles that add up to 180°

So, 7x+33+70=180
Simplify
7x+103=180
Subtract 103 from both sides.
7x=77
Divide both sides by 7.
x=11

Answer 2

Answer: It would be 11.
