Question

In the figure if line l || line m, what is the value of x?​

Answer 1

To find value of x we need to find value of y.

from figure, 3y= 2y + 25 because these are alternate angles.

therefore, y = 25

and 2y +25 = x + 15 these are opposite angles.

as we know y = 25,

x + 15 = (2× 25)+ 25

x + 15 = 50 + 25

x = 75 - 15

x = 60

This is the required answer.

Answer 2

Ans---X = 60
