Homework Statement

Find the direction of vector R counterclockwise to the + x axis

Homework Equations

The Attempt at a Solution

This kind of threw me off balance. I know to get the direction of the vector R for the problem is arctan (5.07/10.87) which gives me 25.

However the answer is 181 degrees.

What am I doing wrong?

Thank you

So are you saying that R points in the negative x-axis direction?
Or are there more facts to this problem?
