Question

..(07.01 LC)
Look at the triangle:
What is the value of cos xº? (1 point)

Answer 1

`\cos x=15/ 17`

Explanation:

Recall the mnemonics SOH-CAH-TOA.

The CAH means the cosine ratio is the ratio of the adjacent side to the hypotenuse.

From the given triangle;

`\cos x=(Adjacent)/(Hypotenuse)`

The side adjacent to the
`x\degree` is 15cm and the hypotenuse is 17cm.

We substitute the values to get;

`\cos x=(15)/(17)` or
`\cos x=15/ 17`.
