Question

A tangent PQ at a point P of a circle of radius 5 cm meets a line through the centre O at a point Q so that OQ =12 cm . length of PQ is :

A) 12cm B) 13cm c) 8.5cm d) √119cm

Answer 1

hey mate ⭐


here is your answer..

option (D)


Because ,

PQ =

$\sqrt{{OQ }^{2} - {OP}^{2} } \\ \\ \sqrt{ {12}^{2} - {5}^{2} } \\ \\ \sqrt{144 - 125} \\ \\ \sqrt{119cm}$
