Answer:
20m
Step-by-step explanation:
First, we need to figure out the distance of the line that comes from vertex C. In order to provide you with the theorem,I'll need to name the intersection between A and B, so I'll be calling it D from now on.
So, let's start with a formula to figure out CD: AD/CD = CD/BD
Using the formula above, we can figure out the length of CD:
16/CD = CD/9
CD^2 = 144
CD = 12m
Second, we can use the pythagorean theorem (a^2 + b^2 = c^2) to solve for AC:
16^2 + 12^2 = AC^2
256 + 144 = AC^2
400 = AC^2
AC = 20 m
Therefore, your answer as to the distance across the pond is 20m.
