МатематикаВопрос:
AB + CD - ? A rhombus ABCD has side lengths AB = 6 and BC = 10. What is the sum of the lengths of sides AB and CD?
Ответ:
Краткое пояснение: В ромбе все стороны равны. Следовательно, AB = BC = CD = DA.
Пошаговое решение:
- Так как ABCD — ромб, то все его стороны равны.
- Дано: AB = 6. Следовательно, CD = 6.
- Находим сумму AB + CD: 6 + 6 = 12.
Ответ: 12
