You can put this solution on YOUR website!
Let legs and hypotenuse = \"+a\", \"+b+\", and \"+c+\"
\n" ); document.write( "(1) \"+a%5E2+%2B+b%5E2+=+c%5E2+\"
\n" ); document.write( "(2) \"+a+%2B+b+%2B+c+=+2015+\"
\n" ); document.write( "(3) \"+a%2Fb+=+7%2F11+\"
\n" ); document.write( "--------------------------
\n" ); document.write( "\"+a+\" would be the shsorter leg
\n" ); document.write( "There are 3 equations and 3 unknowns, so it's solvable
\n" ); document.write( "(3) \"+a+=+%28+7%2F11+%29%2Ab+\"
\n" ); document.write( "and
\n" ); document.write( "(2) \"+c+=+2015+-+a+-+b+\"
\n" ); document.write( "(2) \"+c+=+2015+-+%28+7%2F11+%29%2Ab+-+b+\"
\n" ); document.write( "(2) \"+c+=+2015+-+%28+18%2F11+%29%2Ab+\"
\n" ); document.write( "----------------------------------
\n" ); document.write( "\"+a%5E2++=+%28+7%2F11+%29%5E2%2Ab%5E2+\"
\n" ); document.write( "----------------------------------
\n" ); document.write( "(1) \"+%28+49%2F121+%29%2Ab%5E2+%2B+b%5E2+=+%28+2015+-+%28+18%2F11+%29%2Ab+%29%5E2+\"
\n" ); document.write( "(1)
\n" ); document.write( "Multiply both sides by \"+121+\"
\n" ); document.write( "(1) \"+170b%5E2+=+491287225++-+72540b+%2B+324b%5E2+\"
\n" ); document.write( "(1) \"+154b%5E2+-+72540b+%2B+491287225+=+0+\"
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "You can use qudratic formula to find \"+b+\", then
\n" ); document.write( "use (3) to find \"+b+\"
\n" ); document.write( "Check my math -the numbers are pretty huge !
\n" ); document.write( "
\n" ); document.write( "
\n" );
