The hypotenuse of a right triangle is four times then length of one of the legs.
let x = length of one leg
then
4x = length of the hypotenuse
:
The length of the other leg is square root 735 feet.
Find the length of the leg and hypotenuse.
:
x^2 + %28sqrt%28735%29%29%5E2 = (4x)^2
which is:
x^2 + 735 = 16x^2
735 = 16x^2 - x^2
735 = 15x^2
divide both sides by 15
49 = x^2
x = sqrt%2849%29
x = 7 is one leg
then
4(7) = 28 is the hypotenuse
and
sqrt%28735%29 ~ 27.111 ft is the other leg
