Th pitch of a roof

From Rob: I am trying to determine how much to add for roof pitch. I guess the best way would be to use a right triangle as an example.
The base of the triangle is always 12 inches. The leg pointing straight up is a variable. I will say 6" in this example. By changing the variable how can i determine how much longer the hypotenuse than the base expressed in percent or decimal. Answered by Stephen La Rocque.
