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

the variables x and y vary inversely with a constant variation of 7. Use the variation formula, k=xy, to find why when x=9

dolphi86 [110]

1.Make y the subject

k = xy

k/x = xy/x

y = k/x

2.Substitute

y = k/x

y = 7/9

y = 0.777......

y = 0.8 (Answer)

To confirm

k = xy

k = 9 × 0.8

k = 7.2

k = 7 (constant)

Hope it helps☺
