3. Using the Pythagorean theorem, find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse is 10 feet long.
Using Pythagoras: hypotenuse squared = leg 1 squared + leg 2 squared. Therefore (10*10) = (8*8) + (x * x). 100 = 64 + (x * x). 100 = 64 + (sq rt 36). Sq rt 36 = 6. The other leg is 6 feet long.

Weegy: The length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse is 10 feet long is 6 feet. Solution: Hypotenuse ^2= base^2 + alt^2 , 10^2 = 8^2 + other leg ^2 , 100-64 = other leg^2 , other leg = (36)^1/2 = 6. (More)
