I don't know if c should be a side or the hypotenuse,
\n" ); document.write( "If it should be a side:
\n" ); document.write( "a*2 + c^2 = b*2
\n" ); document.write( "7^2 + c^2 = 81
\n" ); document.write( "49 + c^2 = 81
\n" ); document.write( "c^2 = $\"sqrt%2832%29\"$
\n" ); document.write( "c = 2 $\"sqrt%282%29\"$
\n" ); document.write( "If it's a hypotenuse
\n" ); document.write( "a^2 + b^2 = c^2
\n" ); document.write( "7^2 + 9^2 = $\"sqrt%28130%29\"$
\n" ); document.write( "c = $\"sqrt%28130%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
