Question

7.
2. In this figure 'o' us the center of the cicle 4
LBOC = 120 the find value of a​

Answer 1

Answer:

Here, ∠AOC + ∠COB = 180°

∠AOC = 180° - ∠COB

= 180° - 120° = 60°

Now, x = 1/2 ∠AOC = 1/2 × 60° = 30°

Step-by-step explanation:

In the given figure, O is the centre of the circle. If∠BOC= 120°, then find the value of x.

Answer 2

Answer:

Here, ∠AOC + ∠COB = 180°

∠AOC = 180° - ∠COB

= 180° - 120° = 60°

Now, x = 1/2 ∠AOC = 1/2 × 60° = 30°
