**1. Homework Statement**

a) If Vx = 18.00 units and Vy = -15.50 units, determine the magnitude of V.

b) Determine the angle of V with respect to the x-axis.

**2. Homework Equations**

**3. The Attempt at a Solution**

Yeah, Part B is pretty much the only one I don't get .

a) Answer is 23.75

b) I'm not too sure about what the whole "respect to the x-axis" means. The angle does lie in the fourth quadrant, so I assumed the answer is to do 360 degrees - the angle (i got 40.73) and get 319.27 but that didn't work. I'm down to one try for the answers, so I have to get this one right.

Thanks!
