A man walks 100 m due West from a point X to Y, he then walks 100 m due North to a point Z. Find the bearing of X from Z.

A.
195^{o} 
B.
135^{o} 
C.
225^{o} 
D.
045^{o}
Correct Answer: Option B
Explanation
tan(theta) = (frac{100}{100}) = 1
(theta) = tan^{1}(1) = 45^{o}
The bearing of x from z is N45^{o}E or 135^{o}
