Answer:

210° , 330°

Step-by-step explanation:

using the sides of the 30- 60- 90 triangle

with legs 1, $\sqrt{3}$ and hypotenuse 2 , then

$sin^{-1}$ $\frac{1}{2}$ = 30° ← related acute angle

since $sin^{-1}$ - $\frac{1}{2}$

then angle is in third / fourth quadrants , then required angles are

180° + 30° = 210° ← in third quadrant

360° - 30° = 330° ← in fourth quadrant
