Question

attended PQ at a point P of a circle of radius 5 cm meets a line through the centre O at a point o q is 12 centimetre height PQ is​

Answer 1

Step-by-step explanation:

The line drawn from the centre of the circle to the tangent is perpendicular to the tangent. ∴ OP ⊥ PQ By Pythagoras theorem in ΔOPQ, OQ2 = OP2 + PQ2 ⇒ (12)2 = 52 + PQ2 ⇒PQ2 = 144 - 25 ⇒PQ2 = 119 ⇒PQ = √119 cm
