In the figure, find PRQ

A.
66(frac{1}{2})^{o} 
B.
62(frac{1}{2})^{o} 
C.
125^{o} 
D.
105^{o} 
E.
65^{o}
Correct Answer: Option B
Explanation
Angle subtended at any part of the circumference of the circle (frac{125^o}{2}) at centre = 360^{o} – 235^{o} = 125^{o}
(bar{PQR}) = (frac{125}{2})
= 62(frac{1}{2})^{o}
