Asked by Fred

A man walks at a steady course bearing 122 degrees from A to B. If A is 86 m further west than B, find (to the nearest metre) how far the man has walked.
Answered by Steve
draw a diagram. Clearly the distance x is found using

86/x = sin 36°
Answered by Matt
X/Sin90 = 86/Sin58
X = 101.41m (2 d.p.)
