The sum of the measures of the interior angles of a polygon Is five times the sum of the measures of its exterior angles, one angle at each vertex. How many sides does the polygon have?
\n" ); document.write( "---
\n" ); document.write( "The sum of the exterior angles is ALWAYS 360 degrees.
\n" ); document.write( "--
\n" ); document.write( "So, sum of the interior angles is 5*360 = 1800 degrees.
\n" ); document.write( "----
\n" ); document.write( "Let n be the number of sides:
\n" ); document.write( "Equation:
\n" ); document.write( "(n-2)180 = 1800
\n" ); document.write( "n-2 = 10
\n" ); document.write( "n = 12 sides
