Answer:

The answer to your question is AC = 9.9

Step-by-step explanation:

To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.

cos α = $\frac{adjacent side}{hypotenuse}$

Solve for hypotenuse

$hypotenuse = \frac{adjacent side}{cos\alpha }$

Substitution

hypotenuse = $\frac{9}{cos 24}$

Simplification and result

hypotenuse = 9.85
