Q.1 (B)(iii) In the following figure, ray PQ touches the circle at point Q, PQ = 12, PR = 9. Find PS.
[Figure: P is a point outside the circle; ray PQ is a tangent touching the circle at Q; a secant from P cuts the circle first at R and then at S, so P – R – S; the line through P, R, S carries an arrow beyond S.]
