In the given figure, O is the centre of the circle. AB and AC are tangents drawn to the circle from point A. If $\angle BAC = 65°$, then find the measure of $\angle BOC$.

Question

Accepted Answer

Step 1: $\angle BAC + \angle BOC = 180°$ (angle between tangents and angle at centre are supplementary)
Step 2: $\Rightarrow \angle BOC = 180° - 65° = 115°$
