Answer 1

Answer:

28 is the correct answer

Step-by-step explanation:

3y+2y+40=180

5y=140

y=28

Answer 2

Answer:

28

Step-by-step explanation:

We know that AOB forms a straight line.

The angle of a straight line is 180 degree.

Now, Angles AOB + DOC + COB = 180  ----- Linear Pair

40 + 3y + 2y = 180

40 + 5y = 180

5y = 180 - 40

5y = 140

y = 140/5

y = 28
