It's easiest to just draw a diagram.
Start out at (0,0) and draw a line 3.7 long, at an angle of 15deg up from horizontal.
Now you have a right triangle, with hypotenuse 3.7, and
height = 3.7 sin 15 = 0.96 (north)
base = 3.7 cos 15 = 3.57 (east)
A person walks 15.0° north of east for 3.70 km. How far due north and how far due east would she have to walk to arrive at the same location?
