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 :)
