First simplify the square root of 1/25
-√1/25
Rewrite using the quote by rule for radicals.
-√1/√25
Any root of 1 is 1
-1/√25
Simplify the denominator. (find the square root of 25)
-1/5
The result can be shown in both exact and decimal forms.
Exact form: -1/5
Decimal form: -0.2

Trigonometric ratios are useful in calculating the side lengths of a triangle.
- The length of the zip line is 222.5 ft
- The height where the ladder rests against the tree is 38.6 ft
- The distance between the base of the ladder and that of the tree is 10.4 ft
- The distance between the base of the tree and the spot where the zip line is anchored to the ground is 219.1 ft
<u>(a) Length, z</u>
First we calculate (h) using the following sine ratio

Make h the subject

Next, we calculate (z) using the following sine ratio

Make z the subject

Substitute 


Hence, the length of the zip line is 222.5 ft
<u>(b) The height, h</u>
In (a), we have

Evaluate

Hence, the height where the ladder rests against the tree is 38.6 ft
<u />
<u>(c) The distance, b</u>
To do this, we make use of the following sine ratio

Make b the subject


Hence, the distance between the base of the ladder and that of the tree is 10.4 ft
<u />
<u>(d) Distance, B</u>
To do this, we make use of the following sine ratio

Make B the subject

Substitute 


Hence, the distance between the base of the tree and the spot where the zip line is anchored to the ground is 219.1 ft
<u />
