Question

find the lenght of the tangent drawn from a point whose distance from the centre of a circle is 5cm and radius of the circle is 3cm​

Answer 1

Answer:

Given: PQ is a tangent to the circle intersect at Q. OP = 5 cm and OQ = 3 cm.

To find: PQ

Proof:

In rt.△ OQP, by Pythagoras theorem

Therefore the length of the tangent from a point is 4 cm.
