Magnitude and direction

    Displacement: Magnitude And Direction (urgent)

    1. The problem statement, all variables and given/known data

    Jim walks 100m due south, 60m due east, and then 20m due north. What is his net
    displacement (both magnitude and direction)?

    2. Relevant equations

    I know how to find the net displacement by the magnitude of the distance...
    using the d = sq. rt ( (x2-x1)^2 + (y2-y1)^2 )

    but i dont know how to express the direction?

    PLEASE HELP!!

    3. The attempt at a solution

    So he goes 80m S and 60m E. If it were a triangle with 80m is a down pointing leg and 60 as a right pointing leg, how would you find the direction the hypotenus goes in?

    Think vectors.
