In △ABC, ∠A = 66°, and AB and AC are produced to points D abd E , respectively . If the bisectors of angle CBD and angle BCE meet at the point O, ∠BOC to :
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 57°
In the above triangle ∠A = 66°
∠BOC = 90° - ∠A/2
∠BOC = 90° - 66°/2
∠BOC = 90° - 33°
∠BOC = 57°
