sum of measures of interior angles=
\n" ); document.write( "180(n-2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "set it equal to 2100 and 2400\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "180(n-2)=2100
\n" ); document.write( "180n-360=2100
\n" ); document.write( "180n=2460
\n" ); document.write( "n=13.6667\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "180(n-2)=2400
\n" ); document.write( "180n-360=2400
\n" ); document.write( "180n=2760
\n" ); document.write( "n=15.3333\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".5 or over round up
\n" ); document.write( "less than .5 round down\r
\n" ); document.write( "\n" ); document.write( "n=14 or 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The polygon has 14 or 15 sides.
