What's a good strategy for finding the angle for each quadrant?
@MarkFL

Thanks.

I would write something like:

\(\displaystyle v_x=350\cos\left(95^{\circ}\right)\)

\(\displaystyle v_y=350\sin\left(95^{\circ}\right)\)

How about for negative angles (any quadrant) or positive ones in the 3rd and 4th quadrants?

You could use \(0\le\theta<2\pi\) or \(-\pi\le\theta<\pi\).
