Displacement w/ vectors question

  1. Nov 1, 2007 #1
    My physics text really sucks at explaining this... I consulted my pre-calc text but it sent me on a three chapter tangent of sinusoids which really don't concern me now. i'm sort of running out of time so, plz help. Here's the question (I need how to solve it not just a number and unit)

    A mail-man drives 22 miles N, than drives South-East (forming a -60 degree angle with the x-axis) for 60 miles. What is his displacement from his origional location?

    ok I've only worked with right traingles thus far and feel kind of noob-ish. Do I find the sin of each angle and add them maybe?:confused:

    Why don't you add the components of each displacement to find the total.

    do you mean to make right triangles out of every side? I suppose that might work.
