Solve for b.
a^2 + b^2 = c^2
13^2 + b^2 = 16^2
169 + b^2 = 256
b^2 = 87
b = 9.33 km
Russell Gossman is training for the Olympics. He wants to know the distance across Lake Royal so he can write how far he went in his training logbook each day. If from one point on the shore to one side in 13 km and from the same point to another side of the lake is 16 km. What is the approximate length in km of the lake?
This is in Pythagorean Theorem. I understand how to do it but the problem is saying that a leg is 13 km and the hypotenuse is 16 km. How to you find the length of the other leg?

All you need to do, is subtract 16^2 by 13^2 and then you get the answer. I am not going to tell you what the answer is, because I am not that nice.
