Question

In the given figure, angle POQ =100 and <PQR = 30°, then
find <RPO
7. In figure, angle ABC =120°, Where Al and Care points
on the circle with centre 0. Find <OAC ?​

Answer 1

Answer:

We know that angle subtended by an arc at the centre is double the angle subtended by it at the remaining part of the circle.

∠PRQ =1/2 ∠POQ

= 1/2 x 110°

= 55°
