In the unit circle, if ? = 300, what are the coordinates of (X, Y)?

Question

I'm currently in Algebra 2 and currently doing an ACT Prep and i'm stuck on this question.

Answer 1

if ? means the angle θ and the arc has measure 300º, then the coordinates are (1/2, -√3/2)

Answer 2

The standard equation for a unit circle is x^2 + y^2 = 1, where r is 1 (thus "unit" circle)--it is centered on the origin.  Some possible coordinates of (x,y) are (0,1), (1,0), (0,-1) and (-1,0) for whole number answers.  I'm confused about what "?" stands for here--the wording of this question.
