In the given figure O is the center of the circle. If ∠PRQ = 84°, then the value of ∠OPQ is?
Answer & explanation
Correct answer: option 4
∠POQ = 2 × ∠PRQ = 2 × 84 = 168°
(Angle formed on the center is double the angle formed on the circumference by same are)
PO = OQ = radius
2∠OPQ = 180° - 168° = 12°
∠OPQ = 6°
