Сумма углов параллелограмма прилежащих к одной стороне равна 180 градусов.

Возьмём меньший угол за X, тогда большой угол - X+14. Составим уравнение: X+X+14=180. Решим его:

2X+14=180

2X=166

X=83 - Это меньший из углов. Найдём больший угол:

83+14=97

Ответ: 97 градусов

Сумма смежных углов равна 180. Разность равна 14.

{ a+b = 180

{ a - b = 14

a = b + 14

b + 14 + b = 180

2b = 180 - 14 = 166

b = 166/2 = 83 градуса

a = b + 14 = 83 + 14 = 97 градусов

gulfairuzjazikbai: Ответ будет 97 градусов

These two very old people are the father and mother of Mr Bucket. Their names are Grandpa Joe and Grandma Josephine. And these two very old people are the father and mother ___1__ Mrs Bucket. Their names are Grandpa George and Grandma Georgina. This is Mr Bucket. This is Mrs Bucket.Mr and Mrs Bucket have a small boy whose name is Charlie. This is Charlie.How d'you do? And how d'you do? And how d'you do again? He is pleased ___2__ meet you.The whole ___3__ this family — the six grown-ups (count them) and little Charlie Bucket — live together __4___ a small wooden house __5___ the edge of a great town.The house wasn't nearly large enough __6__ so many people, and life was extremely uncomfortable__7__ them all. There were only two rooms in the place altogether, and there was only one bed. The bed was given __8___ the four old grandparents because they were so old and tired. They were so tired, they never got out __9___ it. Grandpa Joe and Grandma Josephine on this side, Grandpa George and Grandma Georgina __10___ this side. Mr and Mrs Bucket and little Charlie Bucket slept in the other room, __11__ mattresses on the floor. In the summertime, this wasn't too bad, but __12___ the winter, freezing cold draughts blew __13____ the floor all night long, and it was awful. There wasn't any question of them being able __14____ buy a better house — or even one more bed to sleep in. They were far too poor __15___ that.Mr Bucket was the only person in the family __16__ a job. He worked in a toothpaste factory, where he sat all day long ___17__ a bench and screwed the little caps ___18___ to the tops of the tubes of toothpaste after the tubes had been filled. But a toothpaste cap-screwer is never paid very much money, and poor Mr Bucket, however hard he worked, and however fast he screwed on the caps, was never able to make enough to buy one half of the things that so large a family needed. There wasn't even enough money to buy proper food for them all. The only meals they could afford were bread and margarine __19___ breakfast, boiled potatoes and cabbage for lunch, and cabbage soup for supper. Sundays were a bit better. They all looked forward __20__ Sundays because then, although they had exactly the same, everyone was allowed a second helping.The Buckets, of course, didn't starve, but every one of them — the two old grandfathers, the two old grandmothers, Charlie's father, Charlie's mother, and especially little Charlie himself — went __21___from morning till night with a horrible empty feeling in their tummies. Charlie felt it worst of all. And although his father and mother often went without their own share of lunch or supper so that they couldgive it _22__ him, it still wasn't nearly enough for a growing boy. He desperately wanted something more filling and satisfying than cabbage and cabbage soup. The one thing he longed for more than anything else was . . . CHOCOLATE.
