We know that the length of the side opposite 30 is half of the hypotenuse length,
\n" ); document.write( "thus this side is 13/2. To find the length of the side opposite 60 we use \r
\n" ); document.write( "\n" ); document.write( "Pythagorean theorem: \"13%5E2-%2813%2F2%29%5E2=x%5E2\"=> \"x%5E2=+169-169%2F4=3%2A169%2F4\"=>\r
\n" ); document.write( "\n" ); document.write( "\"x=sqrt%283%2A169%2F4%29\"=> \"x=%2813%2F2%29sqrt%283%29\".
\n" ); document.write( "
\n" );
