Using the calculator in degree mode, we can convert the complex number to trigonometric form by using the "angle" function. 
The result is: $10\angle{-50.78^\circ}$
Rounding to the nearest hundredth: $10\angle{-50.77^\circ}$ or $10\angle{-50.78^\circ}$.
Option D has the angle closest to $-50.78^\circ$, so it is the best choice.
