Homework Help: Geometry problem

  1. Apr 30, 2006 #1
    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!

    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.
