You can put this solution on YOUR website!
you would use Pythagorus theorem:
\n" ); document.write( "square on hypotenuse=sum of squares of other two sides.
\n" ); document.write( "In your case diagonal is hypotenuse.
\n" ); document.write( "so if (d)is diagonal and x and y the two sides it connects
\n" ); document.write( "\"d%5E2=x%5E2%2By%5E2\"
\n" ); document.write( "add\"x%5E2\" and\"y%5E2\"
\n" ); document.write( "then find\"sqrt%28d%5E2%29\"
\n" ); document.write( "Pete
\n" ); document.write( "
\n" );
