Answer:
1. angle P and angle T are equal, so angle T = 2x + 5
angle S and angle O are also equal, so angle O = 3x - 10
since, S and T are supplementary angles
S + T = 180
(3x - 10) + (2x + 5) = 180
5x = 185
x = 37
substituting x
angle P = 79
angle O = 101
angle S = 79
angle T = 101
2. (OS + PT)/2 = ER
[(3x - 2) + (2x + 10)]/2 = 14
(5x + 8)/2 = 14
5x + 8 = 28
5x = 20
x = 4
substituting x
OS = 10
PT = 18
hope it helps
