Homework Statement



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

Homework 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!!

Draw the path on graph paper then draw a line back to the start - the direction is just the angle of this line ( usually given from the horizontal x axis )
The magnitude is the length of this line.
