Find the length of the third side. If necessary, round to the nearest tenth.
Looking for one leg of right triangle
pythg theorem hypotenuse^2 = leg1 ^2 + leg2 ^2
9^2 = 5^2 + leg2 ^2
legg 2 = sqrt (9^2 - 5^2) = sqrt 56 = 2 sqrt 14
Ahhh, you beat me to it! Also, for the guest, use a calculator to round to nearest 10th :P
