Question

In the given figure, O is the centre of the circle,

∠BAC = 40°. Find x:​

Answer 1

Answer:

x= 80°

Step-by-step explanation:

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

=80°
