    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...)

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

    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
