Сумма всех углов треугольника = 180 градусам.
Так как треугольник равнобедренный, то его углы при основании равны.
Значит сумма углов при основании = 53+53=106,
тогда у гол между боковыми сторонами = 180-106=74 градуса

There are lots of stories about fantasy animals. Here is some information about four famous fantasy animals. Unicorns were beautiful creatures like horses. They had a long pointed horn in the middle of their foreheads. Unicorns were a sign of good luck, but only honest people could see them.
Centaurs were wild creatures. They were half-man, half-horse. Most centaurs were soldiers but one centaur was different. His name was Chiron. He was a famous teacher. When he died he changed into a star called Sagittarius. Chinese dragons were good, friendly and intelligent. They were made from the parts of nine animals: a snake’s body, a fish’s scales, a clam’s stomach, a tiger’s feet, an eagle’s claws, a camel’s face, a deer’s antlers, a cow’s ears and golden eyes.
