Answer:
∠BOC = 125° and ∠AOP = 125
Step-by-step explanation:
∠QOD = 180°
∠AOQ = y° ∠AOP = x° ∠POD = 5°
x:y = 5:2
let take constant z
x = 5z y = 2z
⇒ ∠QOD = ∠AOQ + ∠AOP + ∠POD
⇒ 180° = y° + x° + 5°
⇒ 180° = 2z + 5z + 5°
⇒ 180° - 5° = 7z
⇒ z = 175/7
⇒ z = 25°
⇒ x = 5z = 25×5 = 125°
⇒ ∠AOP = ∠BOC (vertical opposite angle)
⇒ ∠BOC = 125° and ∠AOP = 125
