Пусть х-DC                                                                                                                          Тогда (х+8) - BD                                                                                                                       По условию задачи  BC - 24 см                                                                                  Составим и решим уравнение:х+(х+8)=24                                                                х+(х+8)=24                                                                                                               2х=24-8                                                                                                                   2х=16                                                                                                                   х=16:2                                                                                                                                      х=8                                                                                                                                         DC-8 cм                                                                                                                               BD-16 cм
