The question is somewhat wrong as it as already given that L and M intersect at 40 degrees.

What is asked to find is not clear

angle between two sides (Streets) L and M is 40 degree
the angle between the sides (Streets) N and M is 90 degrees
Hence angle between sides (Streets) L and N should be 180-(40+90)=50 degree (Option E)

Streets L, M and N are straight and level, and they intersect to form a triangle. If streets L and M intersect at a 40° angle and if street N is perpendicular to street M, at what acute angle do streets L and N intersect?

(A) 30°
(B) 35°
(C) 40°
(D) 45°
(E) 50°

$$\angle$$ LM = 40
$$\angle$$ NM = 90
$$\angle$$ LN = 180 - (40+90)
= 50
