Question

In the given figure, find the value of y.​

Answer 1

Step-by-step explanation:

angle AOF=EOB=90°

SO AOE=FOB=90°

AND COE=DOF=30

30+3y=90

3y=60

y=20°

Answer 2

Answer:

30 degree

Step-by-step explanation:

In the given figure,

∠AOF  = ∠BOE = 90°           [ Vertically opp angle ]

So, ∠EOC + ∠BOE + ∠DOB = 180°           [ Linear equation ]

   =    30° + 90° + 3 y = 180°

   =     120 + 3 y = 180

   =      3 y = 180 - 120

   =       y = 60/2

  =       y = 30

Hence, the value of y is 30 degree.
