Question

In the figure,the value of x is 30. What should be the value of y in order to get line l ll line m?​

Answer 1

Answer:

hope it will help you.....

Step-by-step explanation:

given-

x = 30

l // m

to find-

y = ?

solution-

as we know,

sum of x and y is 180

then,

x+y=180

30 + y =180

y=180 - 30

y= 150°

Answer 2

Answer:

150

Step-by-step explanation:

Given : x = 30

Let us imagine that x and y are co - interior angles in order to make line l // m.

Therefore , x + y = 180

30 + y = 180

y = 180 - 30

y = 150

Hence y = 150 in order to make the line l parallel to line m.

ADDITIONAL INFO : THE SUM CO-INTERIOR ANGLE IS 180. IN OTHER WORDS CO-INTERIOR ANGLES ADDS TO GIVE 180.
