Answer:
cos(θ) = 6/9
Step-by-step explanation:
An easy way to remember your sin, cos, and tan is with the acronym SOHCAHTOA which stands for
Sin Opposite over Hypotenuse
Cosine Adjacent over Hypotenuse
Tangent Opposite over Adjacent
Since 6 is the adjacent side to θ, and 9 is the hypotenuse, cos(θ) = 6/9
