Автор ответа: ridyrnd

Ответ:

58°

Пошаговое объяснение:

om = od (радиусы)

od перпендикулярно db (радиус и касательная, значит угол odb = 90°)

угол dom = дуга md : 2 = 32° (угол вписанный)

угол obd = 180° - (90°+32°) = 58°

Помогите пожалуйста. Which of these reasons can be a motivation for yo
u? why? why not? write a composition about it (5-10 sentences). Start with your motivation. You can use information and ideas from the text.
Текст:
You'll be able to travel all over the world and communicate with people everywhere. This is really nasty. First of all, you don't want to travel abroad — you are quite happy at home. Secondly, why should you talk to a waiter in a hotel in Egypt or listen to an English-speaking guide on an excursion to the Tower of London? Thirdly, who wants to talk to the sales assistant in a French shop or ask somebody for directions in Poland? And finally, you don't want to meet those cool guys who came to your town on an exchange programme. All these people can just learn Russian, can't they? You'll always get the news first. This may make you really nervous. Th saying "No news is good news" is right. If you learn to speak English, you' have to watch the international television networks: CNN and the BBC tha broadcast news faster and more professionally than smaller national network You can get them everywhere in the world, so you'll never get any peace an quiet. You'll get access to information on any subject. Nobody needs that muc knowledge. We live in the information age anyway, and you already get moi information than you want. If you make a bad mistake and learn just or language, English for example, you'll be able to surf the net day and nigh because most of the websites on the Internet are in English. You will also t able to read any book on any subject. Most books in the world have English translations. But reading all night and surfing the net are really bad for yoi health, don't you agree? You'll learn all about your favourite music group. Imagine that one da you'll be able to understand the words of all your favourite English sonЈ What if they are not as good as you thought? Or think: you'll be able to watch British and American films in the origin language. Who knows, you may never want to listen to bad translations agai Don't start! And worst of all: You'll find a fantastic job and earn a lot of money. Horribl isn't it? Stay away (держитесь подальше) from English and you'll be safe becau top-class diplomats, politicians, scientists and artists everywhere in the woi use English to communicate with each other. You don't want to be one them, do you! Almost all business in Russia today is international. Even a secretary h to write letters in English and speak English on the phone. And if you a really unlucky and get an important job, you may have to go to internatior conferences, read international business newspapers and make reports English. So follow our advice: Don't learn English
