Use the Formula $a \sin B \theta + b \cos B \theta = \sqrt { a ^ { 2 } + b ^ { 2 } } \cos ( B \theta - C )$

question 55

Multiple Choice

Use the formula $a \sin B \theta + b \cos B \theta = \sqrt { a ^ { 2 } + b ^ { 2 } } \cos ( B \theta - C )$ ,where $C = \arctan ( a / b ) , a = 3 , b = 7 , B = 2$ to rewrite the trigonometric expression in the following form.​ $y = \sqrt { a ^ { 2 } + b ^ { 2 } } \cos ( B \theta - C )$ ​ $a \sin B \theta + b \cos B \theta$ ​

• A) \(\sqrt { 58 }\) \(\cos ( 2 \theta + 0.4049 )\)
• B) \(\sqrt { 58 }\) \(\cos ( 2 \theta - 0.4049 )\)
• C)7 \(\cos ( 2 \theta - 0.4049 )\)
• D)3 \(\cos ( 2 \theta - 0.4049 )\)
• E)3 \(\cos ( 2 \theta + 0.4049 )\)
