Question

If l and m are parallel lines in the following image then what is the measure of angle x?

Answer 1

angle X is 35 degree
X=180-90-(180-125)=35

Answer 2

Since l and m are parallel lines

when two parallel lines are crossed by transverse line then
The pairs of angles on opposite sides of the transversal but inside the two parallel lines are called Alternative interior angles
and are equal to each other.

Therefore,

x+90=125
x=125-90
x=35

so,
Ans is x=35 degree

Answer 3

angle x = 35 degree
125-90 = 35
