Автор ответа: babonka1

Если угол AOD равен 86, значит угол DOB=180-86=94, а т.к. OK биссектриса, то DOK равен половине DOB и равен 47 градусам

World weather
What’s the weather like where you live? Is it hot and sunny all the time? Or cloudy with mostly grey skies? We asked students from all over the world to tell us what the weather’s like where they live. Here are their answers.

James, 14, London
London is famous for its cloudy weather. The sky is usually full of clouds and quite grey, although sometimes we have nice weather, like in the spring. Then we have lots of rainy days and it’s nice because the rain makes everything green. Some people don’t like the weather here. They would like to have more sun and fewer clouds, but I like it.

Rania, 13, Egypt
In Egypt, the weather is usually hot. My family and I live near the sea, but we don’t have a lot of rain. In fact, most of my country is a desert. But there’s lots of water near the River Nile, and we use this water to wash and to grow fruit and vegetables. In the winter, it’s colder and often cloudy, but we never have snowy or frosty weather. Winter doesn’t last long, but at least it’s cool for a few months before it gets hot again!

Jessica, 15, California
It’s just like in films where I live – sunny weather all year. I know I should love it, but when the weather is sunny and warm every day, you get tired of it. It doesn’t rain a lot here, but we get thunderstorms sometimes. I’ve seen bright flashes of lightning before, followed by loud thunder. It’s quite exciting. The good thing about the weather in California is you can go to the beach almost every day.
