Let length of the hypotenuse = 3x and length of given leg be x feet.

then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81

so x = 9 and 3x = 27

Hypotenuse is 27 feet and the leg equals 9 feet.

Choose the lowest common denominator.

Brilliant_brown [7]

1) 8

2) $-\frac{3}{4}=-\frac{6}{8}$ , so it is equal to $-\frac{6}{8}+\frac{5}{8}$

3) 1/8
