Answer 1

Answer:

1. 60°

2. 60°

3. 6 cm

Step-by-step explanation:

OA = OB (radius of same circle)

triangle AOB is isosceles triangle.

∠OAB = ∠OBA

∠OAB + ∠OBA + ∠AOB = 180°

∠OAB + ∠OBA = 180-60 = 120°

∠OAB =  ∠OBA = 120/2 = 60°

AS all angles of this triangle are equal, triangle is equilateral (having all sides same)

thus Radius = OA = OB = 6 cm
