Azip line starts on a platform that is 40 feet above the ground. the anchor for the zip line is 198 horizontal feet from the base of the platform.

I attach the full question in the image below

The answer is L = 202 feet

Step-by-step explanation:

The setup  of this problem can be modeled as a right triangle, and therefore we can apply Pythagoras's theorem

"The square of the longest side of a right triangle is the sum of the square of each of the other two sides"

In this case, the longest side is equal to the length of the zip line (L)

L^2 = A^2 + B^2

Where,

A = 40 feet

B = 198 feet

L = sqrt ( (40)^2 + (198)^2)

L = sqrt ( 40804)

L = 202 feet

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
