10 см;  13 см;   13 см;

Объяснение:

Дано: ΔАВС, АВ=АС;  Р=36 см. АК-КС=3 см. АВ - ? ВС - ?  АС - ?

Отрезки касательных проведенных к окружности из одной точки, равны между собой.

Пусть АМ=АК=х см, тогда СК=СН=ВН=ВМ=х-3 см.

Имеем уравнение

х+х+х-3+х-3+х-3+х-3=36

6х=48;  х=8

АМ=АК=8 см;  КС=СН=ВН=ВМ=8-3=5 см.

АВ=ВС=8+5=13 см

ВС=5+5=10 см
