Вчера прошла московская регата для 11 классов. Предлагаем вам забавную задачку с нее 🛳

Задача. В пятиугольнике 𝐴𝐵𝐶𝐷𝐸: 𝐴𝐵 = 𝐷𝐸, ∠𝐴 = ∠𝐸 = 45°, 𝐵𝐶 ⊥ 𝐶𝐷, 𝐴𝐸 = 10, 𝐵𝐶 + 𝐶𝐷 = 6. Найдите площадь пятиугольника.

Попутного вам ветра сегодня 🌬

The channel appears to be part of the broader information war that has developed following Russia's invasion of Ukraine. The Kremlin has paid Russian TikTok influencers to push propaganda, according to a Vice News investigation, while ProPublica found that fake Russian fact check videos had been viewed over a million times on Telegram. False news often spreads via public groups, or chats, with potentially fatal effects. "There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said. You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies.
