1) xy =120,,, given two legs product =120
\n" ); document.write( "2) x^2 +y^2 = z^2 (pythagorous) (z=hypotenuse)
\n" ); document.write( "3) x +y+z= 40,,,,,given
\n" ); document.write( "4) sides are integers,,,,given
\n" ); document.write( ".
\n" ); document.write( "checking all of the factors of 120,, for even integer for z if z^2 = x^2 + y^2
\n" ); document.write( ".
\n" ); document.write( "only the 8 - 15 - 17 , rt triangle sides fit
\n" ); document.write( ".
\n" ); document.write( "checking : sum = 40,,ok
\n" ); document.write( ".
\n" ); document.write( "factors of 120, 1*120, 2*60, 3*40, 4*30, 5* 24, 6* 20, 8*15, 10*12 \n" ); document.write( "
