3) 20°

Объяснение:

Подсказка

Через точку C проведите прямую, параллельную MN, до пересечения с прямой AB в точке K. Треугольник ACK – равнобедренный.

Решение

  Через точку C проведём прямую, параллельную MN, до пересечения с прямой AB в точке K. Поскольку M – середина BC и  MN || CK,  то отрезок MN – средняя линия треугольника BCK. Поэтому  KN = BN,  а так как N – середина AD, то  AK = BD = AC.  Значит, треугольник ACK – равнобедренный.

  BAC – внешний угол равнобедренного треугольника ACK, поэтому  ∠BNM = ∠BKC = ½ ∠BAC = 20°.
