First, you need to find ∠PTS because ∠PTS is complementary to ∠PTU and once you find the measurement, you just have to subtract it from 180.
∠PTS is a corresponding angle to ∠NPR so just find x:
3x = 5x - 32
Subtract 5x from both sides:
3x = 5x - 32
-5x
-2x = -32
Divide both sides by -2:
-2x = -32
/-2 /-2
x = 16
Now just plug it into your equation:
∠PTS = 5(16) - 32
∠PTS = 80 - 32
∠PTS = 48°
To find ∠PTU, subtract ∠PTS from 180:
∠PTU = 180 - 48
∠PTU = 132°
Now for ∠QTP:
Subtract ∠QTU from ∠PTU. ∠QTU = 89 because of corresponding angles:
∠QTP = 132 - 89
∠QTP = 43°
