Объяснение:

∠1=∠2 (вертикальные) ⇒ ∠1=∠2=50/2=25°;

∠3=∠4 (вертикальные);

∠1+∠3=180° (смежные) ⇒ ∠3=(180-25)=155°.

Напишите пожалуйста как читать по русски, НЕ ПЕРЕВОД!!!Darr the dolphin lived in the clear blue waters of the Red Sea. He was a very happy and playful dolphin, but he was also mischievous. Darr loved to play tricks on the other creatures that lived under the sea with him.

One day, Aneesa, the octopus, was sorting out her yarn. She had eight different colors of yarn on her eight different legs. It had taken her a long time to untangle them. Darr snuck into Aneesa's cave, swam right up behind her, and yelled "BOO!" She was so scared that she dropped all of the yarn and it fell into a big messy pile. In terror, she swam to the back of the cave to hide.

Darr started to laugh. Aneesa peeked and saw that it was Darr who had scared her and that the eight colors of yarn were all mixed up into a tangled mess. "You'll be sorry for this one day, Darr. Someday you'll be in big trouble and I won't help you!" she warned.

Another time, Darr, the dolphin, swam into an oyster bed. All of the oysters were sleeping, allowing time for their pearls to grow inside of them. Darr snuck in quietly, gently pried open each and every oyster, and took the pearls out. He switched them around and put different ones back into the wrong oysters. When he finished, he swam behind some coral to wait and watch.

When Omar oyster woke up and checked his precious pearl, he was that it wasn't his. Amal oyster did the same. Soon all the others were awake and checking their pearls, only to discover that none of them had their own. They began to get angry and started accusing each other of switching them, because theirs had been bigger and better.

Darr couldn't stand it any longer. He started squealing with laughter. The oysters stopped their arguing and looked angrily at Darr. Omar said, "One day, Darr, your dirty tricks will get you into big trouble." Darr just laughed harder and harder and then swam away.
