уголC=180-(90+45)

уголС=45 градусам следовательно DCB-Равнобедренный

CD=DB-8см

угол A=уголB

AB=8см+8СМ

AB= 16 см.

July 17th was coming. It would be Mark’s _________THIRTEEN_________ birthday. His Mum asked him what he _________WANT_________ as a gift. Mark answered at once that his dream was to have a telescope to watch the stars. Mum _________SHAKE_________ her head doubtfully. She knew that Mark enjoyed learning about space but a telescope was a _________EXPENSIVE_________ present than they had planned. After dinner the parents had a discussion about the present. “I think we should give Mark the telescope,” Dad said.
“But we ________SPEND__________ all our savings already,” Mum responded.
“We bought some new furniture and paid for our holidays. I wish we _________CAN_________ buy him this present but we really can’t.”
“I think, we can,” Dad smiled. “Look, I’ve got an old friend, Nick, whose father was interested in astronomy. His father died many years ago, and Nick keeps all his things in the attic. I think he _________AGREE_________ to sell us his telescope at half price.” Nick ________PLANT__________ roses in the garden when Mum and Dad arrived at his house. “Yes, sure,” he said. “There are lots of _________BOX_________ in the attic.

It was the middle of November and Tina felt down and depressed. Late autumn was the _________BAD_________ season of the year. It often _________RAIN_________, and Tina had to spend most of her time indoors. Because of this, she really welcomed the changes in her school routine. The school administration introduced a new class - a dance class. But not everyone was happy! The boys said that it ________BE__________ a waste of time. They often missed the class and, when they attended, they _________NOT/LISTEN_________ to the teacher’s instructions but tried to make fun of everything. “I wish we _________HAVE_________ a class for girls only,” Tina thought. The Junior Dance Competition _________HOLD_________ in their town every year. It was a spectacular show. “Your dancing _________IMPROVE_________ every day,” the teacher said one day. “If you go on like this, you _________HAVE_________ a chance to take part in the Dance Competition next month.” Tina imagined herself wearing a beautiful dress and elegant shoes on her _________FOOT_________.

Cindy liked parks. She took long walks in the nearby park almost every day. Her classmates, however, _________NOT/SHARE_________ her interest and Cindy usually walked alone. Cindy’s parents worried that she _________HAVE_________ no friends. “I wish you _________SPEND_________ more time with your classmates. Don’t you feel bored in the park?” “It’s ok, Mum, I just feel much ________GOOD__________ alone than with people who can’t understand me,” Cindy usually answered. “Parks are a lot more fun to spend time in than hanging out in a shopping centre.” And her mother didn’t know what to say. One day, Cindy returned from the park very excited. “Guess, who I met in the park!” she said, and she told her parents the whole story. “I _________WALK_________ along the central avenue when I saw a group of people. They ________BE_________ students of the Biology faculty of the university. They told _________I_________ about the plan to rearrange the park. A large lake is going to be made in the centre. There will be wild animals there like hares, squirrels and even _________FOX_________. Yesterday, the plan _________APPROVE_________ by the City Council and work starts tomorrow. I want to join the volunteer team!”

When I was at school, I spent two summers at my grandfather’s. They were the _________GOOD_________ holidays I’ve ever had. Grandpa lived alone in a country cottage near a small river. Grandpa’s hobby was making birdhouses. He always said that he _________NEED_________ a hobby to fill his free time. Grandpa’s workshop was full of all kinds of tools. There _________BE_________ a big table, hammers, nails, paints, and what not. And all the tools _________KEEP_________ carefully in their places. That was Grandpa’s number one rule. The _________TWO_________ rule was, “Never buy a new tool if the old one still works.” In the workshop, when he _________MAKE_________ the birdhouses, I asked him lots of questions about birds. He _________KNOW_________ a lot about them! He could tell one bird from another by their songs and footprints. I was surprised that Grandpa _________NOT/PAINT_________ the birdhouses in bright colours. He explained to ________I__________ that birds prefer natural colours that make their houses more difficult to notice and, for that reason, safer.
