Jim has put a fence along the side AC of the triangular patch of land shown below.


A right angle triangle ABC is shown having length of one leg equal to 6 meters. The measure of angle ABC is 90 degrees. A fence is shown on the hypotenuse of the triangle. The length of the fence is 10m, the same as that of the hypotenuse.

What is the length of side AB?

Just recognize that this is a scaled-up 3-4-5 triangle.
