Answer 1

Answer:

Let ∠Q = ∠R = x, ∠p = 60°

But ∠P + ∠Q + ∠R = 180°

∴ 60° + x + x = 180°

⇒ 60° + 2X = 180°

⇒ 2x = 180° - 60° = 120°

⇒ x = 120°/2 = 60°

∴ ∠Q = ∠R = 60°

Hence, ∠R = 60°

Answer 2

Answer:

90°

Step-by-step explanation:

60°+30°+X=180°. ( angle sum property)

90°+X=180°

x=180°-90°

x=90°
