Homework Help: The difference between north of east and east of north

  1. Feb 6, 2016 #1
    1. The problem statement, all variables and given/known data
    In what direction is your friend from the starting point after skiing 3km east and then 1.5km north?

    2. Relevant equations
    angle = tan-1(1.5km/3km)
    = 26.6 degrees
    3. The attempt at a solution
    they want the answer in terms of degrees "north of east "
    not sure what the rules are for the angle that I should use with north of east
    as compared to that to use with east of north ? 90-26.6 = 63.4
    is there any rule regarding clock-wise and counter-clock wise that would be useful?

    Compass directions are given in a CW (not counter-CW) direction ordinarily.

    For compass directions, north is 0 degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees.

    This is the compass rose, with the directions also indicated in degrees:
