Trig Equation

a) Use the special triangles and the CAST rule to solve the equation 2sinx + $$\sqrt{3}$$ = 0 for the domain interval 0 $$\leq$$ x $$\geq$$ 360.

b) What feature of the graph, in the form y = asinx + b, would show the solutions?

a) sinx = -$$\sqrt{3}$$/2
x = -60 degrees

180 + 60 = 240 degrees
360 - 60 = 300 degrees

b) Can anybody give me a clue as to what this is asking? I have absolutely no idea :(
