Задача. Точки 𝑀 и 𝑁 выбраны на биссектрисе 𝐴𝐿 треугольника 𝐴𝐵𝐶 таким образом, что ∠𝐴𝐵𝑀 = ∠𝐴𝐶𝑁 = 21°. Пусть 𝑋 — точка внутри треугольника такая, что 𝐵𝑋 = 𝐶𝑋 и ∠𝐵𝑋𝐶 = 2∠𝐵𝑀𝐿. Найдите ∠𝑀𝑋𝑁.
Пусть у вас сегодня найдется ответ на все вопросы 🌌

Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. The fake Zelenskiy account reached 20,000 followers on Telegram before it was shut down, a remedial action that experts say is all too rare.
