Multiple Choice

Use the product-to-sum formulas to rewrite the product as a sum or difference. $8 \sin 65 ^ { \circ } \cos 25 ^ { \circ }$

• A) \(8 \left( \sin 90 ^ { \circ } + \sin 40 ^ { \circ } \right)\)
• B) \(4 \left( \cos 90 ^ { \circ } + \cos 40 ^ { \circ } \right)\)
• C) \(4 \left( \cos 90 ^ { \circ } - \cos 40 ^ { \circ } \right)\)
• D) \(\left( \sin 90 ^ { \circ } + \sin 40 ^ { \circ } \right)\)
• E) \(4 \left( \sin 90 ^ { \circ } + \sin 40 ^ { \circ } \right)\)
