Answer:

65

Step-by-step explanation:

hello dear!

suppose that y and x are the straight line.

as we know that:

115=y (reason: corresponding sides are equal in parallel lines)

now,

y + x= 180(straight angle)

now we keep the value of y i.e. 115

115+x=180

x=180-115

x=65

as there is parallel lines m and n, the angles between them i.e. corresponding angle are equal to each other .

so therefore, the value of x = 65°

hope it helps!
