**mysterychicken**, Saturday, June 6, 2009 at 11:04amYes; this is what my book says:

If the hypotenuse of a right triangle has length c, and the legs have lengths a and b, then c^2= a^2 + b^2

In the second, the vertical, half the base, and the side form the right triangle, you are looking for the vertical a.
