\n" ); document.write( "The statement of the problem as shown is defective; there are an infinite number of right triangles that satisfy the given requirements.

\n" ); document.write( "Let the longer leg be x; then the shorter leg is x-3. The hypotenuse needs to be at least 15.

\n" ); document.write( "\"x%5E2%2B%28x-3%29%5E2%3E=15%5E2\"
\n" ); document.write( "\"x%5E2%2Bx%5E2-6x%2B9%3E=225\"
\n" ); document.write( "\"2x%5E2-6x-216%3E=0\"
\n" ); document.write( "\"x%5E2-3x-108%3E=0\"
\n" ); document.write( "\"%28x-12%29%28x%2B9%29%3E=0\"

\n" ); document.write( "x is greater than 12 or x is less than -9. Obviously the negative number makes no sense.

\n" ); document.write( "ANSWER: the longer leg can be ANY length greater than 12 feet.
