Question

In the figure, find angle PQR, if O is the centre of the circle
and angle POR = 60°
(1) 120° (2) 135° (3) 150° (4) 105°​

Answer 1

Since there is no figure

This is only an assumption

If angle POR=60°

Then

2×Angle PQR=angle POR

(Angle subtended at centre of circle is double the angle subtended by it on any other part on the circle)

Angle PQR=1/2×60°

Angle PQR=30°
