Answer:

x is 30°

Step-by-step explanation:

I. Solve the question with

   -1 + sinx = -1/2

       sinx = -1/2 + 1

      sinx = 1/2

II. When sine value is y and cosin value is x

The only y value = 1/2 is only value is 30° or [tex]\frac{\pi}{6}[/tex]

[tex]\frac{\pi}{6} = (\frac{\sqrt{3} }{2} , \frac{1}{2} })[/tex]

That makes x = 30° is the right answer.

Hope that help :)
