активно пользуемся двумя правилами:
1. градусная мера развернутого угла равна 180°
2. сумма углов в треугольнике также равна 180°

HelpMeeeeeeeeeee: Спасибо большое)))
coffeёкmug: дико извиняюсь, мною допущена грубая ошибка: во втором задании угол равен не 54, а 44. следовательно, второй угол равен не 36, а 46
coffeёкmug: даже в последней строчке при проверке не смутило, что получается 88, стыд да и только х)
HelpMeeeeeeeeeee: ) спасибо
HelpMeeeeeeeeeee: Извините
HelpMeeeeeeeeeee: В первом задании нужно было найти углы треугольника АСD
HelpMeeeeeeeeeee: И сравнить отрезки АВ и СD
coffeёкmug: м, пардон. еще косяк(и кто меня учил считать). угол ВАС=50, не 60. а касательно сторон могу сказать только, что СD больше
