Question

In the given figure, O is the centre of
the circle and P, Q and R are three points on it
If Q = 50° and R=30°,
then findi) P ii) QOR
​

Answer 1

In ∆PQR using angle sum property we have. P + Q + R =. 180°

P + 50° + 30° = 180°.

P = 1000

using angle subtended the item angle QOP is half angle P
