no spam plz......​

Answer 1

Answer:

20 ° is ur answer

Step-by-step explanation:

As the lines are concurrent at O ,

so ,

=> angle BOF = angle EOA ( vertically opposite angles) = 5y

=> since , CD is a straight line ,

so angle will be 180°

=> angle COE + angle EOA + angle AOD = 180°

=> 2y + 5y + 2y = 180°

=> 9y = 180°

=> y = 20°
