To find the number of sides of the polygon using the given sum of interior angles\r
\n" ); document.write( "\n" ); document.write( "we need to use the formula
\n" ); document.write( "(n-2)180 and the given number 3780\r
\n" ); document.write( "\n" ); document.write( "so (n-2)180 = 3780
\n" ); document.write( " 180n - 360 = 3780
\n" ); document.write( " 180n - 360 + 360 = 3780 + 360
\n" ); document.write( " 180n 0 = 4140
\n" ); document.write( "
\n" ); document.write( " 180n/180 = 4140/180
\n" ); document.write( "
\n" ); document.write( " n = 23 \n" ); document.write( "

\n" );
