Question

In the given figure (ii) given below, O is the centre of the circle. Calculate the values of x and y. ​

Answer 1

Answer:

We know, the angle subtended by an arc of a circle at the centre is double the angle subtended by it at any point on the remaining part of the circle

Hence,In given circle,

∠POR=2∠PQR

Therefore ∠POR=2×40

o

=80
