Помогите пожалуйста! Найди боковые стороны треугольника, если угол между ними равен 60 градусам, а площадь 16 корень из 3.​


edsem1403: Точнее можно?
ilja23p8au9w: всё, что известно
edsem1403: Какой треугольник?
edsem1403: Прямоуголбний?
ilja23p8au9w: такой, у которого острый угол 60 градусов
edsem1403: Если прямоугольный то есть решение!
ilja23p8au9w: да, прямоугольный
edsem1403: Как помогло?

Тут недостаточно условий. Площадь треугольника = 1/2*a*b*sinC
ab*sin60= 16 корней из трех * 2
a*b=64
Если в условии треугольник равносторонний или равнобедренный, то боковые стороны = корень из 64 = 8.
Скорее всего в условии сказано какой треугольник.

ilja23p8au9w: уточнений нету, но смею предположить, что он прямоугольный.

Ответ:

Если у прямоугольном треугольнике один угол 60 тогда тот что напротив 30. Есть теорема если у прямоугольном треугольнике есть угол 30 то, катет что напротив у 2 разы меньше чем прилегающий.

Пусть одна сторона будет х тогда вторая 2х.

За теоремой Пифагора гипотенуза равна √(х)до квадрата+(2х)до квадрата

Составим уравнение: х*2х*√(х)до квадрата+(2х)до квадрата=16√3

х*2х*5(х)до квадрата=16√3

2х*6(х)до квадрата=16√3

2(х*3(х)до квадрата)=16√3

х*3(х)до квадрата=8√3

4(х)до квадрата=8√3

(х)до квадрата=2√3

х=√2√3
