Step-by-step explanation:
![\sin {}^{ - 1} ( - \frac{1}{2} ) =](https://tex.z-dn.net/?f=%20%5Csin%20%7B%7D%5E%7B%20-%201%7D%20%28%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%20%3D%20)
Using the identity,
![\sin( - x) = - ( \sin(x) )](https://tex.z-dn.net/?f=%20%5Csin%28%20-%20x%29%20%20%3D%20%20-%20%28%20%5Csin%28x%29%20%29)
![\sin( \frac{1}{2} ) = \frac{\pi}{6}](https://tex.z-dn.net/?f=%20%5Csin%28%20%5Cfrac%7B1%7D%7B2%7D%20%29%20%20%3D%20%20%5Cfrac%7B%5Cpi%7D%7B6%7D%20)
so
![\sin {}^{ - 1} ( \frac{ - 1}{2} ) = - \frac{\pi}{6}](https://tex.z-dn.net/?f=%20%5Csin%20%7B%7D%5E%7B%20-%201%7D%20%28%20%5Cfrac%7B%20-%201%7D%7B2%7D%20%29%20%20%3D%20%20-%20%20%5Cfrac%7B%5Cpi%7D%7B6%7D%20)
Convert to degrees.

Answer:
Your 1. does not show the triangle, so I may not help with it but know that sin = opposite over hypotenuse, cos = adjacent over hypotenuse, and tan = opposite over adjacent
2. 5/13, just do the adjacent over hypotenuse
