The exterior angle of a regular polygon is (2x + 2) degrees and its interior angle is (9x - 9) degrees. How many sides does the polygon have?
\n" ); document.write( "----
\n" ); document.write( "The angles are supplementary::
\n" ); document.write( "(2x+2) + 9x-9 = 180
\n" ); document.write( "11x - 7 = 180
\n" ); document.write( "11x = 187
\n" ); document.write( "x = 17
\n" ); document.write( "----
\n" ); document.write( "The exterior angle = 2x+2 = 36
\n" ); document.write( "------
\n" ); document.write( "# of sides = 360/36 =10
