the length of one leg is 6ft. The length of the hypotenuse is 3ft longer than the other leg. Find the length of the hypotenuse and the other leg.
\n" ); document.write( ".
\n" ); document.write( "Let x = length of \"other leg\"
\n" ); document.write( "then
\n" ); document.write( "x+3 = length of hypotenuse
\n" ); document.write( ".
\n" ); document.write( "applying Pythagorean theorem:
\n" ); document.write( "x^2 + 6^2 = (x+3)^2
\n" ); document.write( "x^2 + 6^2 = (x+3)(x+3)
\n" ); document.write( "x^2 + 36 = x^2+6x+9
\n" ); document.write( "36 = 6x+9
\n" ); document.write( "27 = 6x
\n" ); document.write( "27/6 = x
\n" ); document.write( "4.5 feet = x (other leg)
\n" ); document.write( ".
