The ratio of the interior angle to the exterior angle of a regular polygon is 5:2. Find the number of sides of the polygon
\n" ); document.write( "---------
\n" ); document.write( "5 + 2 = 7
\n" ); document.write( "7 sides
\n" ); document.write( "=================
\n" ); document.write( "PS That doesn't always work.
\n" ); document.write( "Here's the long version:
\n" ); document.write( "5x + 2x = 180
\n" ); document.write( "x = 180/7
\n" ); document.write( "Ext angles = 2x = 360/7
\n" ); document.write( "# of sides = 7.\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
