Question

Please help I’m stuck

Answer 1

Explanation:

In parallelogram, sum of adjacent angles = 180

x +15 + 6x - 10 = 180

x +6x + 15 - 10 = 180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175/7

x = 25

∠Q = x + 15 = 25+ 15 = 40°

∠R = 6x - 10 = 6*25 - 10 = 140

In parallelogram, opposite angles are equal

∠P = ∠R = 140°

∠S =∠R = 40°
