По условию задачи, ABCD — это трапеция с основанием AD. По определению трапеции, её основания параллельны. Следовательно, прямая AD параллельна прямой BC. В виде формулы это записывается как $AD \parallel BC$.

Рассмотрим плоскость BMC. Данная плоскость определена тремя точками B, M и C. Прямая BC проходит через две из этих точек, а значит, прямая BC целиком лежит в плоскости BMC. Это можно записать как $BC \subset (BMC)$.

По условию, точка M не лежит в плоскости трапеции (ABCD). Прямая AD, в свою очередь, лежит в плоскости (ABCD). Из этого следует, что прямая AD не может лежать в плоскости BMC. Докажем это от противного: предположим, что $AD \subset (BMC)$. Тогда точки A и D принадлежат плоскости BMC. Так как точки B и C также принадлежат этой плоскости, то все четыре вершины трапеции A, B, C, D лежат в плоскости BMC. Это означает, что плоскость трапеции (ABCD) и плоскость (BMC) — это одна и та же плоскость. Но это противоречит условию, согласно которому точка M принадлежит плоскости (BMC), но не принадлежит плоскости (ABCD). Следовательно, наше предположение неверно, и $AD \not\subset (BMC)$.

Теперь мы можем применить признак параллельности прямой и плоскости, который гласит: если прямая, не лежащая в данной плоскости, параллельна какой-либо прямой, лежащей в этой плоскости, то она параллельна и самой плоскости.

У нас есть все необходимые условия для применения этого признака:
1. Прямая AD не лежит в плоскости BMC ($AD \not\subset (BMC)$).
2. Прямая AD параллельна прямой BC ($AD \parallel BC$).
3. Прямая BC лежит в плоскости BMC ($BC \subset (BMC)$).

На основании этих фактов мы заключаем, что прямая AD параллельна плоскости BMC.

Что и требовалось доказать.

Ответ: Утверждение, что прямая AD параллельна плоскости BMC, доказано.
