Question

Find COS

Answer 1

$\frac{9}{41}$

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,

$\cos(x) = \frac{adj}{hyp}$

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

So

$\cos(a) = \frac{9}{41}$
