Ответ:

Для знаходження довжини діагоналі АС паралелограма ABCD, спочатку потрібно обчислити вектор AC. Вектор AC можна отримати шляхом віднімання вектора AB від вектора AD:

AC = AD - AB

Дано:

Вектор AB = (2, -1, 2)

Вектор AD = (-3, 1, 2)

Обчислюємо вектор AC:

AC = (-3, 1, 2) - (2, -1, 2)

= (-3 - 2, 1 - (-1), 2 - 2)

= (-5, 2, 0)

Тепер, щоб знайти довжину вектора AC, використовуємо формулу для обчислення довжини вектора:

|AC| = √(x^2 + y^2 + z^2)

де x, y і z - компоненти вектора AC.

|AC| = √((-5)^2 + 2^2 + 0^2)

= √(25 + 4 + 0)

= √29

Таким чином, довжина діагоналі АС паралелограма ABCD дорівнює √29.
