Question

find the value of y? in the given figure​

Answer 1

Answer:

180 - 90 + 30 = 60

3y = 60

or , y = 60/3

or , y = 20

Answer 2

Answer:

y is 20°

Step-by-step explanation:

Assume center as O

∠EOB = 90°   (Vertically opposite angles)

∠COE + ∠EOB + ∠BOD = 180°

30° + 90° + 3y° = 180°

3y° + 120° = 180°

3y° = 180° - 120°

3y° = 60°

y° = 60°/3

y° = 20°
