An interior angle x and its explement y were turned to close the horizon. Each angle was observed once direct and once reverse using the repetition method. Starting with an initial backsight setting of 0°00'00" for each angle, the readings after the first and second turnings of angle x were 49°36'24" and 99°13'00" and the readings after the first and second turnings of angle y ere 310°23'28" and 260°46' 56". Calculate each angle and the horizon misclosure.
