Respuesta :

[tex] \frac{9}{41} [/tex]

Step-by-step explanation:

The ratio cosine tell us that

  • In a right angled triangle, the cosine of an angle is the side adjacent to the angle divided by the hypotenuse of the triangle.

In other words,

[tex] \cos(x) = \frac{adj}{hyp} [/tex]

The side adjacent to angle a is 9. The hypotenuse is 41.

So

[tex] \cos(a) = \frac{9}{41} [/tex]
