\n" ); document.write( "recall, the sum of the length of any two sides on a triangle is greater than the length of third side\r
\n" ); document.write( "\n" ); document.write( "so, if the lengths of two sides of a triangle are \"6\" and \"7\",the length of third side is less than \"6%2B7=13\"\r
\n" ); document.write( "\n" ); document.write( "and the third side must be between \"1\" and \"13\" units\r
\n" ); document.write( "\n" ); document.write( " It cannot equal \"1\" and it cannot equal \"13\".\r
\n" ); document.write( "\n" ); document.write( "The only answer that fits in this interval is II. \"5\"
\n" ); document.write( "
