Answer:

Value of opposite ∠2 = 120°

Step-by-step explanation:

Given question:

Quadrilateral inscribed in a circle

Value of ∠1 = 60°

Find:

Value of opposite ∠2

Computation:

In Quadrilateral inscribed in a circle, sum of opposite angle is 180

So,

Value of ∠1 + Value of ∠2 = 180°

60 + Value of ∠2 = 180

Value of ∠2 = 180 - 60

Value of ∠2 = 120

Value of opposite ∠2 = 120°
