Q. 34.6( 136 Votes )

A. 12 cm B. 13 cm

C. 8.5 cm D. 119 cm.

Answer :

(D)

We know that the line drawn from the centre of the circle to the tangent is perpendicular to the tangent.

OP Ʇ PQ

By applying Pythagoras theorem in ΔOPQ,

OP^{2} + PQ^{2} = OQ^{2}

5^{2} + PQ^{2} =12^{2}

PQ^{2} =144 - 25

PQ = cm.
