Each interior angle of a regular is 120 more than each of the exterior angles. How many sides has it?
\n" ); document.write( "---------------------
\n" ); document.write( "Let each exterior angle be \"x\":
\n" ); document.write( "Then each interior angle is \"x+120\":
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "x + x+120 = 180
\n" ); document.write( "2x = 60
\n" ); document.write( "x = 30 degrees
\n" ); document.write( "-----
\n" ); document.write( "Fact: The sum of all of the exterior angles is 360.
\n" ); document.write( "------
\n" ); document.write( "# of ext. angles is 360/30 = 12
\n" ); document.write( "---
\n" ); document.write( "Therefore # of sides is 12
