Question

In figure, find the value of y. A 28° B 40° C 140° D 56​

Answer 1

Answer:

To find:- value of y

Solution:-

In the figure

40+3y+2y=180°(adjacent angles are supplementary)

40+5y=180

5y=180-40

5y=140

y=140/5

y=28

Therefore the angles are

40°

3y=3×28=84

2y=2×28=56

Let's check whether it's correct or not

40+3y+2y=180

40+84+56=180

180=180

L.H.S=R.H.S

hence verified

Answer 2
