Question

Can someone please help me and write out the answer​

Answer 1

Answer:

$- 30$

Step-by-step explanation:

$\sin {}^{ - 1} ( - \frac{1}{2} ) =$

Using the identity,

$\sin( - x) = - ( \sin(x) )$

$\sin( \frac{1}{2} ) = \frac{\pi}{6}$

so

$\sin {}^{ - 1} ( \frac{ - 1}{2} ) = - \frac{\pi}{6}$

Convert to degrees.

$- 30$
