Answer:

angle P+angle Q??

Step-by-step explanation:

Answer 2

Answer:

144°

Step-by-step explanation:

∠P = ∠Q = 2 ∠PRQ

Let consider ∠P = ∠Q = x and ∠PRQ = y

∠Q = 2 ∠PRQ

x= 2y

y = x/2

sum of interior angle of triangle = 180°

x + x + y = 180°

2x + x/2 = 180°

x = 72

∠P = ∠Q = 72°

∠PRQ = 36°

Straight line angle = 180°

so ∠PRS = 180 - ∠PRQ = 180° - 36° = 144°

∠PRS = 144°
