Question

In the figure below, lines m and n are parallel. Line s is perpendicular to line m.

What is the measure of ∠x?
A.
60°

B.
55°

C.
40°

D.
35°

Answer 1

I think it would be 55 only because line P is 145 degrees so because line S is straight it is 90 degrees. So you would subtract the two (145-90) and would come up to B or 55.
