Question 149

Multiple Choice

Use the cofunction identities to find an angle θ that makes the statement true.
- sin⁡(θ+4∘) =cos⁡(θ+6∘) \sin \left( \theta + 4 ^ { \circ } \right) = \cos \left( \theta + 6 ^ { \circ } \right)


A) θ=10∘\theta = 10 ^ { \circ }
B) θ=83∘7\theta = \frac { 83 ^ { \circ } } { 7 }
C) θ=17∘7\theta = \frac { 17 ^ { \circ } } { 7 }
D) θ=40∘\theta = 40 ^ { \circ }
