Відповідь:

основание 7см боковые стороны по 10см

Покрокове пояснення:

в равнобедренном треугольнике боковые стороны равны

пусть основание =х тогда боковая сторона =х+3

составим уравнение

х+2(х+3)=27

х+2х+6=27

3х=27-6

3х=21

х=7 см длина основания

7+3=10 см боковая сторона

Ответ:

Стороны треугольника =

10 см

10 см

7 см

Пошаговое объяснение:

Пусть х - основание, тогда

X + x+3 +x+3 =27

3х +6 =27

3х = 21

Х = 7

Следовательно, боковые стороны = х +3 =10
