You can put this solution on YOUR website!
A 9-sided polygon is called a nonagon.\r
\n" ); document.write( "\n" ); document.write( "3x + 6(145) \r
\n" ); document.write( "\n" ); document.write( "The total value of the angles of a nonagon is 1260 degrees.\r
\n" ); document.write( "\n" ); document.write( "Here is your equation and you can solve for x:\r
\n" ); document.write( "\n" ); document.write( "3x + 6(145) = 1260\r
\n" ); document.write( "\n" ); document.write( "Can you do it now?
