Angles are measured counter clockwise from the positive x axis. A -14 x component means the vector is in the second quadrant. The following equation is used to determine the angle in degrees.
Tan θ = y ÷ x = 22 ÷ 14
Rounded to two significant digits, this angle is 56˚. Since the fourth quadrant, we need to add 90˚. This is approximately 148˚. If you go to the website below, you will see a graph that shows the x and y coordinates for each of the four quadrants. I hope this is helpful for you.
