Step-by-step explanation:
<AOP + < BOP = 180°< being linear pair >
x + 30° + x - 30° = 180°
2x = 180°
x = 90°
Now
<AOP = x + 30° = 90° + 30° = 120°
<BOP = x - 30° = 90° - 30° = 60°
- <AOP is obtuse angle because it is less than 180° but more than 90°.
- <BOP is acute angle because it is less than 90°.
Hope it will help :)❤
