Answer

\boxed{234.7^\circ, 305.3^\circ}

Steps

Step 1 :Find the reference angle in the first quadrant: \(\sin^{-1}\left(-\frac{\sqrt{6}}{3}\right) \approx 54.7^\circ\)

Step 2 :Find the corresponding angles in the third and fourth quadrants: \(180^\circ + 54.7^\circ = 234.7^\circ\) and \(360^\circ - 54.7^\circ = 305.3^\circ\)

Step 3 :\boxed{234.7^\circ, 305.3^\circ}
