Объяснение:

1.а) Сумма углов выпуклого четырёхугольника равна 360⁰.

117⁰+63⁰+33⁰+157⁰=370⁰

360⁰≠370⁰

Ответ: не существует.

b) 180×(n-2)=1080

n-2=1080÷180

n-2=6

n=6+2

n=8

Ответ: 8 сторон.

The Climate of Russia. What is climate? Climate is the average conditions of the weather over a space of earth (the temperature, sunshine, wind, rainfall, etc.). Russia has a varied climate because of its large territory, though almost all of the Russian Federation is situated in the North Temperate Zone.

The very north is a cold treeless region - the tundra. For the greater part of the year the tundra is covered with snow, its rivers and lakes are frozen to a great depth. In May the temperature begins to rise and the gray greenish night is changed into continuous daylight, when the Sun doesn't go below the horizon for several months. Towards the end of August the temperature begins to fall and in less than a month winter sets in again.

The greater part of the Russian Federation has a continental climate: the summers are warm, even hot in some places; the winters are cold. In the North of the country there are no mountains to form a barrier against the cold winds from the Arctic Ocean. Cold air masses move over the land and bring strong frosts. The low winter temperature especially of north-eastern Siberia is due to these cold winds.

The Climate of Great Britain. Great Britain lies between the parallels on which Moscow and Kiev are situated but its climate is much milder than that of this part of Russia, because Great Britain lies on islands and the Gulf Stream flowing near them influences its climate. The January temperature in London is higher and the July temperature is lower in London than in Moscow. The British ports are icefree and the rivers are not frozen throughout the year. In the west of the country there is much rainfall and thick fogs sometimes continue for days and weeks in autumn and winter months. As the result many species of plants do not grow well here, especially green crops. But grasses grow very well all year round providing fresh fodder for cattle.

The Climate of the USA. The climate of the United States of America is as much varied as that of the Russia Federation. As well as Russia the USA has no mountain barrier in the North from the Arctic Sea and the cold Labrador Sea Current. From here masses of cold air flow over the land and lower the temperature, especially in the eastern part of the country. The warm sea current of the Atlantic Ocean - the Gulf Stream - influences the USA climate less because the winds of North America blow from the sea to the land.

Along the western coast the climate of the USA is warm because the Rocky mountains form a barrier from the cold winds of the North and the land here is open to the warm winds of the Pacific Ocean. The climate in the southern part of this coast is hot and dry, the soil arid, the rainfall low and irrigation must be used to cultivate many species of plants.
