• A) \(8 \left( \cos 330 ^ { \circ } + i \sin 330 ^ { \circ } \right)\)
• B) \(8 \left( \cos 98 ^ { \circ } - i \sin 98 ^ { \circ } \right)\)
• C) \(8 \left( \cos 128 ^ { \circ } + i \sin 128 ^ { \circ } \right)\)
• D) \(8 \left( \cos 330 ^ { \circ } - i \sin 330 ^ { \circ } \right)\)
• E) \(8 \left( \cos 98 ^ { \circ } + i \sin 98 ^ { \circ } \right)\)
