    Well we just need to add the 2 vectors, they add up nicely here |dw:1442333921228:dw| Looks like a right triangle doesn't it? *Pythagorea's*

    so you just add 200 and 150? or do you do a^2 + b^2 =c^2?

    The latter :) \[\large Resultant = \sqrt{(150)^2 + (200)^2}\]

    so then the resultant is the direction or magnitude?

    That is the magnitude of the resultant...the direction comes next

    Now the direction, I'm not sure how precise they want you to be...idk if they want "north, south, east, west etc..." or the angle...but I'm going to assume just the previous Well as we can see from my drawing...the resultant looks to be facing SW right?
