Question

Length of the tangent to a circle feom a point 17 cm and feom its center is 8cm then radius of circle ia

Answer 1

Answer: 15

Step-by-step explanation:

Given : A circle with center O. PQ is the tangent ,PQ=17 and OP=8

To Find: OQ

Solution : In ∆ POQ angle OQP=90°

So, OQ=√ PQ^2 - OP^2

=√17^2 - 8^2

= √ 289 - 64

= √ 225

= 15
