Let the length of the hypotenuse = ft
Let the length of the shorter side = ft
Let the length of the longer side = ft
From the Pythagorean theorem,
ft
ft
Complete the square by taking 1/2 of the coefficient of
b, square it, add it to both sides. First add to
both sides
Take the square root of both sides (there is a (-) square root also,
but I can ignore it)
The lengths of the legs are 12 ft and 16 ft
check answer:
OK
