danjs · Answer

are all the angles referenced to the +x direction?

mathmale · Answer

One question at a time, please.
I consider it to be a safe assumption that all angles are measured counterclockwise from the positive x-axis.  Find the vertical and horiz. components of each vector.
If A is the magnitude of a vector, and theta is the angle this vector makes with the positive x-axis, then the horiz. comp. of vector A is |A|cos theta.  What is the vertical comp?
