Question

P is a point in the exterior of a circle having centre O and radius 24. OP = 25. A tangent from P touches the circle at Q. Find PQ.

Answer 1

After drawing circle with tangent,we have seen right angle triangle formed at Q.

In ΔOPQ,

Using Pythagoras Theorem.

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

$PQ^{2} = 25^{2} - 24^{2} = 49$

Hence, PQ = 7

Answer 2

Answer:

the answer of the question is 7
