Ответ:

Угол 7= углу 1

Так как 1 и два в сумме дают 180, то угол один равен 160.

Угол семь= 160

Автор ответа: anobas

Ответ:

170°

Объяснение:

Углы 1 и 2 смежные, в сумме дают 180.

Пусть угол 2 будет x.

x + (x+160) = 180

2x = 20

x = 10

Значит, угол 1 будет равняться 10+160=170

углы 1 и 7 внешние накрест лежащие, они равны

Угол 7 = 170°

Read and decide if the statements are true, false or nothing is known from the text

Maps were made long before reading and writing were invented. The earliest map that we know of is a cave painting on the Lascaux caves in France. The painting shows a part of the summer night’s sky 16500 years ago. Modern astronomers can still understand the night sky shown in the map. A four thousand year old map made by the Ba¬bylonians is still in existence. Many ancient map-makers thought that the world was flat, but explorers like Magel¬lan in the 15th century sailed around the world and helped to make better maps. Besides, measurements taken by satel¬lites show that our planet Is slightly pear-shaped. Satellites have also provided more accurate Information and have helped to see and map parts of the world that were lit¬tle known or never seen by humans before. Satellites have photographed the Amazon rainforest and have shown that the area the size of twenty football pitches is being cut down every minute. Pictures taken from space have also shown that one of the world's largest areas of inland water, the Aral Sea, has been shrinking very quickly. Modern satel¬lite maps show the effects of global warming and pollution and help us to understand the world around us better. More and more drivers nowadays rely on satellite navigation in their cars so the traditional road maps may not be around much longer.
