Помогите!!!Чему равен катет прямоугольного треугольника,если его гипотенуза равна 4 см,а второй катет 2 см

Ответы

Автор ответа: JuliaRichie

по теореме пифагора:

гипотенуза в квадрате = первый катет в квадрате + второй катет в квадрате, значит
первый катет в квадрате = гипотенуза в квадрате - второй катет в квадрате
первый катет в квадрате = 4^2-2^2=16-4=12
первый катет = корень из 12
