Answer:

h = 8

Step-by-step explanation:

Area of rectangle: base * height

So, by substituting the values given, we can write this equation:

A = b * h

26 = 3.25 * h

Divide both sides by 3.25.

h = 8

The length of the repel line using one of the 3 trigonometry ratios will be 186.78 feet.

<h3>How to calculate the length?</h3>

From the information given, Peyton is walking her dog, Willow, on a local trail and the dog falls 153 feet down a ravine.

The length will be calculated thus:

Cos 35° = 153/AC.

AC = 153/cos 35°

AC = 153/0.819

AC = 186.78 feet.

Therefore, the length is 186.78 feet.
