Question

PQ is a chord of a circle with centre O and PT is a tangent at P. A chord PQ is drawn and a chord each from P and Q are drawn namely PR and QR respectively such that point R is in the segment formed by PQ. Given that angle QPT= 700. Find angle PRQ .

Answer 1

Angle PQR = 70 degrees because the angle between a tangent and a chord equals the angle subtended by the chord in the segment opposite the angle.
