Ответ:

∠х=127°; ∠у=53°

Объяснение:

Назовём прямую пересекающую прямые a и b прямой с

∠ в 127° и ∠х - внутренние накрест лежащие углы при параллельных прямых a и b и секущей с ⇒ ∠х=127° (по свойству ║ прямых)

∠х и ∠у - смежные углы (по определению)

∠х+∠у=180° (по теореме о смежных углах) ⇒ ∠у=180°-∠х=180°-127°=53°

P 51 TEXT 2 The Olympic Games
The Olympic Games were held on Greek land in the ancient times. The first Olympic Games took place in 776 B.C. The Olympic Games took place every four years at Olympia and were a part of a religious festi¬val. The four-year interval was called an Olympiad. The games were so im¬portant that even wars were stopped during Olympic Games.
At first, the athletes took part only in race (the sprint). Later, they threw the discus and javelin, then broad jumping and wrestling were added. The Olympic Games were held for more than 1,000 years. The Byzantine Emperor Theodosius abolished them in 394 A.D.
The Games were revived in 1896 to support understanding and friendship among nations. The first modern games were held in Athens, Greece. Young men and women come from all over the world to compete in various sports and represent their country. They live in an Olympic Vil¬lage at the site of the games.
The Olympic Games are organized and governed by the International Olympic Committee (IOC). It sets the program of the games, chooses the city where the games are to be held, and determines the standards of games. Each country has a National Olympic Committee.
The opening ceremony of each Olympic Games is held in a major sta¬dium. The president of the host country usually opens the games. Athletes from Greece march the first and athletes from other countries march after them around the stadium in the parade of Nations. Then, looking at the Olympic Flag, the athletes take the Olympic Oath:
We swear that we will take part in these Olympic Games in the true spirit of sportsmanship, and that we will respect the rules that govern them, for the glory of sport and the honor of our country.
The Olympic Flame is lit with a torch that is brought by a relay of ath¬letes from the ruins of ancient Olympia in Greece. When the Games are finished, the flag is lowered and the flame extinguished.
