Answer :


1. Draw a circle of radius 4 cm taking O as center.

2. Draw radii OA and OB such that OAB = 120°

3. Draw perpendicular at points A and B and suppose the point they intersect is P.

4. PA and PB are required tangents with APB = 60°


In quadrilateral AOBP , By angle sum property of quadrilateral

OAP + OBP + APB + AOB = 360°

90 + 90 + APB + 120 = 360

APB = 60°
