Homework Help: Planes Velocity Problem

  1. Oct 21, 2009 #1
    1. The problem statement, all variables and given/known data

    Kyle is flying a plane due north at 230 km/h as a wind carries it due east at 56 km/h. Find the magnitude and direction of the plane's resultant velocity analytically.
    236.7 km/h (magnitude)
    ° (direction)

    2. Relevant equations


    3. The attempt at a solution

    This should be straightfoward but i guess not?
    I tried:
    tan^-1 (56/230)=13.7 degrees

    Cant seem to figure out why this isnt working it should be straightfoward
