Answer 1

9/15 = 3/5 (simplified)

Explanation:

In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:

`\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}`

The adjacent side is the side that makes up the angle but is not the hypotenuse.

I'm assuming the answer box should ask for cos(theta) rather than cos(x).
