(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The components of Vector A are given as follows

A_{x}=+3.9

A_{y}=-4

The angle measured counterclockwise from the x-axis to vector A , in degrees, is closest to:

2. Relevant equations

arctan(y/x)= theta

3. The attempt at a solution

Hey guys, I got the answer doing Arctan (-4/3.9) +360

My question is how do we know to add 360? Do we always add 360 when it is counterclockwise to the x-axis? and what about if they asked if it was clockwise to the x axis or vica versa for the Y axis, would we have to treat it any different.

Thank you
