use Pythagorean theorem to find the length of hypotenuse \"c\" of right angle triangle:\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=a%5E2%2Bb%5E2\"\r
\n" ); document.write( "\n" ); document.write( "given: two sides \r
\n" ); document.write( "\n" ); document.write( "\"a=+2x%28x%2B1%29\" and \"b=2x%2B1\"
\n" ); document.write( "\"a=+2x%5E2%2B2x\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=%282x%5E2%2B2x%29%5E2%2B%282x%2B1%29%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=4x%5E4%2B8x%5E3%2B4x%5E2%2B4x%5E2%2B4x%2B1\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=4x%5E4%2B8x%5E3%2B8x%5E2%2B4x%2B1\"\r
\n" ); document.write( "\n" ); document.write( "\"c%5E2=%282x%5E2%2B2x%2B1%29%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"c=sqrt%28%282x%5E2%2B2x%2B1%29%5E2%29\"\r
\n" ); document.write( "\n" ); document.write( "\"c=2x%5E2%2B2x%2B1\"\r
\n" ); document.write( "\n" ); document.write( "so, the length of hypotenuse is \"highlight%282x%5E2%2B2x%2B1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
