I have a test tomorrow and this is one of my review problems.
"Circle G is centered at the origin with radius 2. Point H is on the circle at (radical 3, 1). What is the measure of the angle formed by HG and the x-axis?" My teacher told me the answer is 30 degrees, and after much trial with this, I have no idea how to arrive at this answer. PLEASE help as this will most likely be on my test tomorrow!
Thanks,

on second thought, I'll use trig functions to solve. I think this should work.

Yes, it's elementary trig. Think of the tangent of the angle.
