Question

In the adjoining figure , o
is the centre of a circle.
If the length of chord PQ is
is equal to the radius of the circle,
then find angle PRQ.



plz solve this , it's urgent ​

Answer 1

Answer:

Step-by-step explanation:

construction : Join OR,

∵ PQ = OP = OQ(given)

∴ △OPQ is an equilateral triangle  

∴ ∠POQ = 60°  

We know, angle subtended  at a point on a circle is half the angle subtended at the centre.

∠PRQ = 1/2 ∠POQ  

= 1/2 ×  60° = 30°  

angle PRQ = 30 degree
