Answer:
Find m ∠ P and m ∠ Q if ∠ P and ∠ Q are supplementary, m ∠ P = 2 x + 15 , and m ∠ Q = 5 x − 38 .
The sum of the measures of two supplementary angles is 180 ° .
So, m ∠ P + m ∠ Q = 180 °
Substitute 2 x + 15 for m ∠ P and 5 x − 38 for m ∠ Q .
2 x + 15 + 5 x − 38 = 180 °
Combine the like terms. We get:
7 x − 23 = 180 °
