Answer:

b

Step-by-step explanation:

we are given opposite, adjacent and hypotenuse

and said to find cos(B)

recall trigonometric identity [tex]\cos(\theta)=\dfrac{adj}{hypo}[/tex]

let adj and hypo be 9 and 41 respectively

so

[tex] \displaystyle \: \cos( \beta ) = \frac{9}{41} [/tex]

hence our answer is b
