Question

(20) P is a point in the exterior of a circle having centre 0 and radius 24. OP = 25. A tangent from P touches
the circle at Q. Find PQ.
​

Answer 1

Answer:

the correct answer is 7

Step-by-step explanation:

Given: A circle with center O with radius 24

          P is exterior point of a circle

          OP = 25

         Radius of circle is 24 & A tangent from P touches the circle at Q

         Thus, OQ=24

To find: PQ

            OP²=PQ²+OQ²

           25²= PQ² + 24²

           625=PQ² + 576

           PQ²= 625 - 576

          PQ²= 49

          PQ= √49

          PQ= 7
