Ответ:

1)всего 180 градусов веришина 104, значит

180-104/2= 38 градусов углы при основании

2)100+110+70=280, теперь угол BDT=360-280=80

3)прости тут не знаю

4)Проведём прямые от точки B до С и от точки А до D, получим параллелограмм из-за того, чтоAB параллельна CD и AB=CD. Диагонали в параллелограмме равны, это сказано в теореме о диагоналях

5)у меня листочка нету, рисовать надо

Прошу, помогите пожалуйста перевести текст.

 Then it jumped a little more, enough to set the meat shivering and shaking. Then it jumped a lot.

It set the meat shivering and shaking. It set the potatoes dancing up and down. It set the gravy spinning round like a whirlpool, and it set the peas hopping and jumping over the table as if they were alive!

Some of the children looked shocked because they thought Derek was naughty, but some of them laughed because they thought it was funny.

The lady who looked after the children at dinner time was called Mrs North. She did not think it was funny at all.

‘What are you doing?’ she asked angrily.

‘I can’t help it,’ said Derek. ‘It’s the plate’s fault. It’s a jumping plate.’

‘A jumping plate! How can it be?’ said Mrs North. She cleared up the mess and took the plate of food back to the kitchen. She emptied the food into a bin and turned the plate upside down.

‘Perhaps it’s not flat,’ she thought. But it looked flat.

‘Nothing wrong with it,’ she thought, but she did notice a tiny dab of blue paint underneath. Perhaps it was a tiny dab of blue paint or perhaps it was a tiny dab of magic. Who could tell?

The next day the jumping plate was put on the table in front of a little girl called Ann who stayed to school dinners. Ann did not even know it was new and of course, she did not know it was a jumping plate.

On the jumping plate was Ann’s dinner—fish, chips, tomato sauce and peas. The dinner looked the same as all the other dinners. The plate looked the same as all the other plates.

Ann began to eat, and the plate began to jump. At first it jumped only a little—just enough to set the dinner trembling. Then it jumped a little more—enough to set the fish shivering and shaking. Then it jumped a lot.

It set the fish shivering and shaking. It set the chips dancing up and down. It set the tomato sauce spinning round like a whirlpool, and it set the peas hopping and jumping over the table as if they were alive!

Some of the children looked shocked because they thought Ann was naughty, but some of them laughed because they thought it was funny. Mrs North did not think it was funny at all, but she felt very puzzled.

‘What are you doing?’ she asked in a surprised voice.

‘I can’t help it,’ said Ann unhappily. ‘It’s the plate’s fault. It’s a jumping plate.’

‘A jumping plate!’ said Mrs North. ‘How can it be?’

‘It must be the one I had yesterday,’ said Derek.
