Vector {A} points in the negative y direction and has a magnitude of 14 units. Vector {B} has twice the magnitude and points in the positive x direction.
Find the direction and magnitude of {A}+{B} counterclockwise from the positive x axis.

If you add them, magnitude is 14sqrt5
direction: ArcTan 14/28=arctan .5=90+26.56 degrees
