Question

In the below figure , AB , CD and EF are three lines concurrent at O . Find the value of y.

Answer 1

Answer:

y=18°

Step-by-step explanation:

angle AOE= angle BOF=5y (vertically opposite angle)

angle COE+angle EOA+angle AOD= 180°

2y+5y+3y=180°

10y=180°

y= 180/10

y=18°.

Answer 2

Answer:

y=18

Step-by-step explanation:

angle coe+angle eoa + angle aod =180

2y+5y+3y=180

10y=180

y=180/10

y=18
