A boat in the calm seas travels in a straight line and ends the trip 22 km west and 53 km north of its original position. To the nearest tenth of a degree, find the direction of the trip.
-----
Assume the start is at (0,0)
The end is at (-22,53).
----
direction = tan^-1(-53/22) = -67.46
But the angle is in the 2nd Quadrant.
So, direction = -67.46 + 180 = 112.54 degrees
