elliceo1izСоставь уравнение:
х+(х+88)=180;
2х=92;
х=46 - <2
Тогда <1 равен 180-46=134⁰.
Все углы элементарно находятся, как смежные...
Автор:
guido43возьмем за х первый угол, 1угол больше на 88° второго угла,значит х-88°
составляем уравнение:х+х-88°=180°
2х=268°
х=134°
отсюда находим угол 2=134-88=46°
угол 1 и угол 3-смежные,соответственно угол 2 и угол 3 будут равны, угол 4 и угол 1 также равны.
Ответ:углы 1 и 4=134°,а углы 2 и 3=46°
