Write the Complex Number in Trigonometric Form R(c $$r ( \cos \theta + i \sin \theta )$$

Write the complex number in trigonometric form r(c $$r ( \cos \theta + i \sin \theta )$$ ) , with $$\theta$$ in the interval [0 $$\left[ 0 ^ { \circ } , 360 ^ { \circ } \right)$$
- $5 - 5 \sqrt { 3 } i$

A) $5 \left( \cos 330 ^ { \circ } + i \sin 330 ^ { \circ } \right)$
B) $5 \left( \cos 330 ^ { \circ } + \sin i 330 ^ { \circ } \right)$
C) $10 \left( \cos 300 ^ { \circ } + i \sin 300 ^ { \circ } \right)$
D) $10 \left( \cos 150 ^ { \circ } + i \sin 150 ^ { \circ } \right)$
