In a circle with centre O, APB is a tangent at P. If MN is a diameter such that ∠BPN = 52o, then what is the measure of ∠PNM?
Show answer & explanation
Correct answer: A
Explanation
The corrcet answer is option 1 i.e. 38o.
∠BPO = 90° [Tanget makes 90° with the radius always]
So, ∠OPN = 90 - 52 = 38°
Now, ∠OPN = ∠ONP [∵ OP and ON is radius]
∠ONP = 38° = ∠PNM
