Question:
[Section A]
In the given figure, $PA$ and $PB$ are tangents to the circle with center $O$ from an external point $P$. If $\angle APB = 70^\circ$, then $\angle AOB$ is:
(A) $110^\circ$
(B) $70^\circ$
(C) $100^\circ$
(D) $50^\circ$

(A) $110^\circ$
(B) $70^\circ$
(C) $100^\circ$
(D) $50^\circ$
Step-by-Step Solution
Key Concept: Supplementary relation: $\angle AOB + \angle APB = 180^\circ \Rightarrow \angle AOB = 110^\circ$.
Sol. (A) $110^\circ$. [1.0 Mark]
Correct Answer: (A) $110^\circ$
