Explanation / Answer

The directions are perpendicular, so we can use Pythagoras.

d = (16.5² + 24.0²) m = 29.124 m distance from starting point

To find the angle west of north, use
= arctan(west displacement / north displacement)
= arctan(16.5 / 24.0) = 34.50º direction W of N
also written as W 34.50º N
and equal to N 55.5º W.
