How Do You Calculate Direction in Vector Displacement Problems?

Displacement: Magnitude And Direction (urgent)

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 don't know how to express the direction?

PLEASE HELP!

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.
