How many sides does a regular polygon have if the measure of each exterior angle is equal to 120?
\n" ); document.write( "---------
\n" ); document.write( "The sum of the exterior angles of a regular polynomial is 360 degrees.
\n" ); document.write( "----------
\n" ); document.write( "Your Problem::
\n" ); document.write( "# of external angles = 360/120 = 3
\n" ); document.write( "----
\n" ); document.write( "# of sides = # of external angles
\n" ); document.write( "= 3
