Two tangents making an angle of `120^0` with each other are drawn to a circle of radius 6cm, then the length of each tangent is equal to `sqrt(3)` cm (b) 6 `sqrt(3)` cm (c) `sqrt(2)` cm (d) 2 `sqrt(3)` cm

Explanation

We have,

Let the center of circle be O.

Let the tangents be PA and PB from point P into the circle .

`OA=OB=radius=6cm.`

Then,

In the triangle OAP and OBP:

`∠OAP=∠OBP=90^@`
