Options are 

30 degrees
330 degrees
-60 degrees
-30 degrees

I'd say the answer is 330, but how do the fractions come in to this?

You're given a point. Using that point you can find the angle.

Tan(x) = (1/2)/(sqrt(3))/2) = 1/sqrt(3) = sqrt(3)/3

bahrom7893 · Answer

x = Tan^-1(sqrt(3)/3) = 30 degrees
