Answer:

y = 20 degree

Step-by-step explanation:

angle EOA = 5y (being vertically opposite angles)

angle COE + angle EOA + angle AOD = 180 degree (being linear pair)

2y + 5y + 2y = 180 degree

9y = 180

y = 180/9

y = 20 degree

Answer:

y = 20

Step-by-step explanation:

Angles COE and DOF are vertical angles and are congruent.

m<COE = m<DOF = 2y

<BOA is a straight angle and measures 180 degrees.

m<BOF + m<DOF + m<DOA = 180

5y + 2y + 2y = 180

9y = 180

y = 20
