In the diagram, O is the centre, (bar{RT}) is a diameter,

In the diagram, O is the centre, (bar{RT}) is a diameter, < PQT = 33(^o) and < TOS = 76(^o). Using the diagram, find the size of angle PRS.

A.
76^o
B.
71^o
C.
38^o
D.
33^o

Correct Answer: Option B

Explanation

In the diagram, < TRS = (frac{76^o}{2}) = 38(^o)
Hence, angle PRS = 33(^o) + 38(^o)
= 71(^o)
