Step-by-step explanation:
Consider CD line:
180 = <COE + <BOE + < DOB.
But <AOF = < BOE
Then,
180 = <COE + < AOF + <DOB.
180 = 2y + 5y + 3y
180 = 10y.
Therefore,
y = 18.
And,
Angle COE = 2y = 2×18 = 36 degree.
Angle BOE = 5y = 5×18 = 90 degree.
Angle DOB = 3y = 3×18 = 54 degree.
I HOPE THAT THIS MAY HELP YOU
