A regular polygon has 10 sides: 
\n" ); document.write( "a) find the measure of one exterior angle.
\n" ); document.write( "Ext = 360/10
\n" ); document.write( "= 36 degs
\n" ); document.write( "------------
\n" ); document.write( "b) find the measure of one interior angle.
\n" ); document.write( "Int = 180 - 36
\n" ); document.write( "= 144 degs
\n" ); document.write( "c) find the sum of the measures of all interior angles of this polygon
\n" ); document.write( "Int's = 144*10 = 1440 degs
\n" ); document.write( "
\n" );
