the formula for the sum of the interior angles (S) of a regular polygon of n-sides:
\n" ); document.write( "\"S+=+%28n-2%29180\" \r
\n" ); document.write( "\n" ); document.write( "if given that \"S+=++6840\", then we have\r
\n" ); document.write( "\n" ); document.write( "\"6840+=+%28n-2%29180\" ...solve for \"n\"\r
\n" ); document.write( "\n" ); document.write( "\"6840%2F180+=+%28n-2%29180%2F180\"\r
\n" ); document.write( "\n" ); document.write( "\"38+=+n-2\"\r
\n" ); document.write( "\n" ); document.write( "\"38%2B2+=+n\"\r
\n" ); document.write( "\n" ); document.write( "\"n=40\" a polygon called \"tetracontahedron+\"
\n" ); document.write( "
\n" );
