In the given figure, O is centre of the circle. Circle has 3 tangents. If ∠QPR = 45°, then what is the value (in degrees) of ∠QOR?

A. 67.5
B. 72
C. 78.5
D. 65
Answer: Option A
Solution (By Examveda Team)

∠PMO = 90° (Angle made on tangent)
∠QOR = 90° - $$\frac{{\angle {\text{P}}}}{2}$$
∠QOR = 90° - 22.5°
∠QOR = 67.5°
