Решить 1,2,3,4, геометрия, срочно. Created by LegendaryMin228. geometriya-ru

Это же изи, ну ты чего) Задачи на смежные и вертикальные углы. Начнем с первой:угол ab=120, условие.углы ab и a1b1 - вертикальные, следовательно равны. Угол ab1 смежен с углом ab. Соответственно ab=180-120=60Дальше по аналогии:360-70=290 (сумма двух вертикальных углов 2 и 4). Так как они равны, то их градусные меры равна соответственно 145Далее (номер 3)mn=120И последнее: (номер 4){1-2=120{1+2=180угол 1 равен 150, а угол 2 равен 30Угол 3 = 150Угол 4 = 30 Новые вопросы в ГеометрияПомогите решить пж срочноооо надо!!!Срочно!!!!!

MichaelTopKiller Это же изи, ну ты чего) Задачи на смежные и вертикальные углы. Начнем с первой:
угол ab=120, условие.
углы ab и a1b1 - вертикальные, следовательно равны.
Угол ab1 смежен с углом ab.
Соответственно ab=180-120=60
Дальше по аналогии:
360-70=290 (сумма двух вертикальных углов 2 и 4). Так как они равны, то их градусные меры равна соответственно 145
Далее (номер 3)
mn=120
И последнее: (номер 4)
{1-2=120
{1+2=180
угол 1 равен 150, а угол 2 равен 30
Угол 3 = 150
Угол 4 = 30
