Question

In figure,
find
the value of y

Answer 1

Answer:

y = 28

Step-by-step explanation:

We know that,

sum of linear pair of a angle in a straight line = 180°

•°• 40 + 3y + 2y = 180°

= 40 + 5y = 180°

= 5y = 180 - 40

= 5y = 140

= y = 140/5

= y = 28

Therefore,

y = 28

More:

sum of angle of triangle = 180°

Answer 2

28 degree

total angle =180 degree

so

3y+2y=5y

so

40 degree +5y = 180 degree

5y = 140

y = 28 degree
