Question

Explain me all the three questions given in the attachment above​

Answer 1

In the figure,

• 5x + x + 80° + 123° + 85° = 360°

(Angles at a point)

• ⇒ 6x + 80° + 123° + 85° = 360°

• ⇒ 6x + 288° = 360°

• ⇒ 6x = 360° - 288 = 72°

• ⇒ x = 72°/6 = 12°

Now, ∠AOB = 5x = 5 × 12° = 60°

And ∠BOC = x = 12°
