OA is A. Please help me understand how to approach this problem.

since angle PRO = 35 we know that angle QPR = 35 [alternate angles are equal]. Angle made by PQ at the center = 360 - [Angle made by PO at center + Angle made by QR at center + angle made by OR at center] Angle made by PO at center = 2(35) = 70 [angle made by an arc at center = twice the angle made ...

@sandhya: your explanations was very good. thanks. But I have a question the angle of x and y determine the lengths of line segments PQ and RS. thus if the angle x and angle y are equal the length of the line segments would be equal as PS and QR are parallel lines. With the angle of x and y we canno...
