question 6

Multiple Choice

Divide the complex numbers below and leave the result in trigonometric form. $\frac { 5 \left( \cos 100 ^ { \circ } + i \sin 100 ^ { \circ } \right) } { 9 \left( \cos 120 ^ { \circ } + i \sin 120 ^ { \circ } \right) }$

• A) \(\frac { 5 } { 9 } \left( \cos 220 ^ { \circ } + i \sin 220 ^ { \circ } \right)\)
• B) \(\frac { 5 } { 9 } \left( \cos 340 ^ { \circ } + i \sin 340 ^ { \circ } \right)\)
• C) \(45 \left( \cos 220 ^ { \circ } + i \sin 220 ^ { \circ } \right)\)
• D) \(\frac { 5 } { 9 } \left( \cos 340 ^ { \circ } + i \sin 220 ^ { \circ } \right)\)
• E) \(45 \left( \cos 340 ^ { \circ } + i \sin 340 ^ { \circ } \right)\)
