One leg of a right triangle is twice as long as the other leg.
\n" ); document.write( "x = 1 leg
\n" ); document.write( "2x = 2nd leg
\n" ); document.write( ":
\n" ); document.write( "The length of the hypotenuse is square root of 20.
\n" ); document.write( "\"x%5E2+%2B+%282x%29%5E2+=+%28sqrt%2820%29%29%5E2\"
\n" ); document.write( "\"x%5E2+%2B+4x%5E2+=+20\"

\n" ); document.write( "\"x%5E2+=+20%2F5\"
\n" ); document.write( "\"x%5E2+=+4\"
\n" ); document.write( "x = 2 is the 1st leg
\n" ); document.write( "and
\n" ); document.write( "2(2) = 4 is the 2nd leg
