A hiker makes four straight-line walks
A 31 km at 299 degrees
B 32 km at 210 degrees
C 29 km at 59 degrees
D 22 km at 150 degrees
in random directions and lengths starting at
position (41 km, 41 km).
Which vector will return the hiker to the
starting point? All angles are measured in a
counter-clockwise direction from the positive
x-axis.
