Пусть угол А - х, тогда угол B - тоже х, а угол Bad = x/2 рассмотрим треугольник АДБ - угол Б равен 180 градусов -( 110 градусов + x/2) рассмотрим треугольник АБС угол Б равен 180 - 2х потом вычитаем из первого уравнения второе, в правой части у нас ноль (углы Б сократились) в левой части 2x-110-x/2 иксы в правую часть градусы в левую часть переносим итого у нас получается 1,5х=110 градусов x=углу А= углу С= 73 и 1/3 градусов (в ответе переведи в десятичные 73,33) Угол б равен 180 градусов минус 2х = 33 и 1/3 градуса (33.33)
Speaking Task 1. Choose the question from the card on the topic Entertainment and fedia^ prime prime and be ready to answer it after the teacher starts the conversation. Produce a speech by giving extended answers to the questions. Share your ideas with the class.
