Question

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

Answer 1

Answer:

$\cos x=15\div 17$

Step-by-step 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;

$\cos x=\frac{Adjacent}{Hypotenuse}$

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

We substitute the values to get;

$\cos x=\frac{15}{17}$ or $\cos x=15\div 17$.
