Answer:
[tex] - 30[/tex]
Step-by-step explanation:
[tex] \sin {}^{ - 1} ( - \frac{1}{2} ) = [/tex]
Using the identity,
[tex] \sin( - x) = - ( \sin(x) )[/tex]
[tex] \sin( \frac{1}{2} ) = \frac{\pi}{6} [/tex]
so
[tex] \sin {}^{ - 1} ( \frac{ - 1}{2} ) = - \frac{\pi}{6} [/tex]
Convert to degrees.
[tex] - 30[/tex]
