Answer 1

Answer:

i hope this helps   have a good day!   :]

Step-by-step explanation:

∠AOP = x + 30°

∠BOP = x- 30°

But, ∠AOP + ∠BOP = 180°

> x + 30° + x - 30° = 180°

> 2x = 180°

> x = 90°

(i) ∠AOP = x + 30° = 90° + 30° = 120°

(ii) ∠BOP = x - 30° = 90° - 30° = 60°

(iii) ∠AOP is an obtuse angle

(iv) ∠BOP is an acute angle
