In this picture, m∠TPU = 37° and m∠UPS = 5x + 9. If ∠TPU and ∠UPS are supplementary angles, then what is the value of x? A. 134 B. 8.8 C. 26.8 D. 30.4

Answer 1

Watch the video to get the answer! Fun fact: There is more than one way to solve this! For the illustration, you didn't have to draw a triangle but could have just sketched a linear pair!

Answer 2

Supplementary angles add up to 180

37 +5x+ 9 = 180

46+5x =180

5x = 134

x = 26.8
