To draw a pair of tangents to a circle which are inclined to each other at 1000, it is required to draw tangents at end points of those two radii of circle, the angle between which should be-- a)100 , b)50 , c)80 , d)200

I didnt understand the question.plz help

The diagram for the given question is-

You need to find the value of angle AOB.

So in triangle AOP,

 (radius is perpendicular to tangent)

 (line joining the centre and the point of intersection of the tangents bisects the angle between them)
