Автор ответа: Dashule4ka

Пусть оди6 катетравен х, тогда другой х+7. По теореме Пифагора: 13(в квадрате)=(х+7)(в квадрате) + х(в квадрате). Дальше решаем это уравнение. В итоге получаем что х равен 12. Дальше находим катеты: подставляем под х. 1 катет равен 12, второй катет равен 12+7=19. Вот и все)

mansion in the country. He is the chairman of a big

reads the newspapers at breakfast time. Then he gets
dressed. His servants help him. He always wears a smart

business clients. They often go to his favourite night club,
Madame JoJo's. They have dinner, drink champagne and
