document.write( "I'm guessing your hexagon looks something like this:\r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
document.write( "\r\n" );
document.write( "The sum of the interior angles of a polygon is (n-2)·180°.\r\n" );
document.write( "\r\n" );
document.write( "A hexagon has 6 sides so n=6 and the sum of the interior angles is \r\n" );
document.write( "\r\n" );
document.write( "(6-2)·180° = 4·180° = 720°\r\n" );
document.write( "\r\n" );
document.write( "The sum of the 5 given angles is 130°+75°+145°+115°+125° = 590°\r\n" );
document.write( "\r\n" );
document.write( "So the remaing 6th interior angle is 720°-590° = 130°,\r\n" );
document.write( "so we will label it 130° in red. \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "And now y° and 130° are supplementary and have sum 180°.\r\n" );
document.write( "\r\n" );
document.write( "Therefore y° = 180°-130° = 50° \r\n" );
