I have seen this same question more than once in the last few days, but can't seem to find it.
anyway, you should know that sin 30° = 1/2
and the sine is positive in the first and second quadrant,
so clearly x = 30° or x = 150°
check it with your calculator
given that sinx= 0.5,find the value between 90degree and 360degree
