В равнобедренном треугольнике ABC, с основанием AC проведена биссектриса AD,
Найдите угол С, если < ADC=177°​

Объяснение:

4 часа 30 мин=270мин

6 часов 45 мин=405мин

1/270 часть бассейна нальет первый кран за 1 мин

1/405 часть бассейна нальет второй кран за 1 мин

1/405+1/270=5/810=1/162 часть бассейна нальют 2 крана за 1 мин

1:(1/162)=162 мин - время за которое 2 крана наполнят весь бассейн

первый кран был открыт 162 мин

162/270=3/5 - бассейна наполнит первый кран за 162 мин1-3/5=2/5 бассейна нужно наполнить второму крану

2/5 : 1/405=2*405/5*1=810/5=162 мин - Через столько времени бассейн наполнится.

ответ:162 мин. 1-3/5=2/5 бассейна нужно наполнить второму крану

2/5 : 1/405=2*405/5*1=810/5=162 мин - Через столько времени бассейн наполнится.

ответ:162 мин.
