# Math Help - sine angle

1. ## sine angle

How do I solve this? What is the answer?

sin x/2= (square root 3)/2 , -pi<x<pi (this is the range given)

(I had no idea how to put a squre root symbol of the 3...)

hint: $\sin (?) = \frac {\sqrt{3}}2$, what is $?$?

3. sin 60 degrees is (square root 3)/2, therefore the answer is 120 degrees, since the angle is x/2.

4. sin of 60 degrees is (square root 3)/2..........or pi/3........where do I go from here?

5. sin x = (square root 3)/2
means that x is 60 degrees.

sin x/2 = (square root 3)/2

means that x is 120....120/2 = 60
