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

unless if u could do my questions, if not i wouldn't want to

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
