Answer:
If 12 and 14 are both side lengths then we solve for the hypotenuse:
hypotenuse^2 = 12^2 + 14^2
hypotenuse^2 = 144 + 196
hypotenuse^2 = 340
hypotenuse = sq root (340) = 18.4390889146
If hypotenuse = 14, then third side equals:
(3rd side)^2 = 14^2 - 12^2
(3rd side)^2 = 196 -144
(3rd side)^2 = 52
3rd side = sq root (52) = 7.2111025509
