if the interior angle of a polygon is 4 times of its exterior angle,find the no. of sides and the sum of the i nterior angles.
\n" ); document.write( "------------
\n" ); document.write( "Int = 4*Ext
\n" ); document.write( "Int + Ext = 180 degs
\n" ); document.write( "------------
\n" ); document.write( "# of sides n = 360/Ext
\n" ); document.write( "------
\n" ); document.write( "Sum of Int = 180*(n-2)
\n" ); document.write( "
\n" );
