In the above figure, m∠P = 120° and m∠Q = 5x. If angles P and Q are supplementary angles, what is the value of x and the measure of angle Q?

x = 12 and Angle Q measures 60 degrees

Step-by-step explanation:

Supplementary angles are two angles added together to make 180.

So 5x + 120 = 180 subtract 120 from both sides

5x=60 divide both sides by 5

x = 12

Angle Q = 5 times 12 = 60
