Answer:
The answer is option 3.
Step-by-step explanation:
Given that the formula for Cosine Rule is cosθ = adjacent/hypotenuse. So you have to substitute the following values into the formula :
[tex] \cos(θ) = \frac{adj.}{hypo.} [/tex]
Let θ = A,
Let adj. = 9,
Let hypo. = 41,
[tex] \cos(A) = \frac{9}{41} [/tex]
