The hypotenuse of a triangle is one foot more than twice the length of the shorter leg. The longer leg is seven feet longer than

Serhud [2]

Start by calling the shortest side $s$ . We then know that the longer leg (call it $l$ ) is 7 feet longer i.e. $l=s+7$ . We also know that the hypotenuse, $h$ is 1 foot more than twice the short leg i.e. $h=2s+1$ . We now have 3 unknowns but only 2 equations to solve them. Luckily we know this is a right triangle so we can use the Pythagorean Theorem as our third equation:
$a^{2}+b^{2}=c^{2}$
Substituting known values:
$s^{2}+(s+7)^{2}=(2s+1)^{2}$
This is now an equation in one variable and can be solved algebraically for $s$ . Back-substitution can then be used for the other sides.
