I'm interested in a math problem, As shown in the figure, there is a triangle splint. Please draw the inscribed rectangle of the splint so that the long side of the rectangle is on AB, and the ratio of length to width is 2:1 It's not very special. It's not RT △. It looks like the angle cab is 45 degrees,

Do you think this problem is a drawing problem or a calculation problem? If it is a calculation problem, it should have data, and it should be solved by establishing a function according to the length width ratio of the inscribed rectangle. If it is a drawing problem, or ~ please give the figure a full acute angle triangle or obtuse angle triangle? Before sending the figure, I will provide an idea. You can copy the figure into two, that is, the triangle becomes the corresponding parallelogram, A rectangle becomes a square. Can you see it or have a new idea?

In a convex polygon, the sum of the interior angles except one of them is 1205 degrees. Find the sum of the interior angles of the polygon

Because in a convex polygon, 0 is less than 180
So: let this polygon have n sides
（n-2)×180 ＜ 1205+180
(n-2)×180 ＞ 1205+0
Then you can solve it yourself. There must be only one integer solution
After n is obtained, the sum of internal angles can be obtained by the formula

There are three workshops in a factory. The number of people in the first workshop accounts for 1 / 4 of the total number. The number of people in the second workshop is 3 / 4 of that in the third workshop. There are 320 people in the first and second workshops. How many people are there in the three workshops?

The number of people in the first workshop accounts for 1 / 4 of the total number, and the number of people in the second workshop and the third workshop accounts for 3 / 4 of the total number;
The number of people in the second workshop is 3 / 4 of the number in the third workshop, and the number in the second workshop is (3 / 4) / (1 + 3 / 4) = 3 / 7 of the total number in the second workshop and the third workshop;
(3 / 7) x (3 / 4) = 9 / 28 in the second workshop;
1 / 4 + 9 / 28 = 16 / 28 = 4 / 7,
Total number of people in three workshops: 320 (4 / 7) = 560 (people)
equation
There are three workshops with a total of X people, the first workshop with X / 4 people, the second workshop and the third workshop with a total of 3x / 4 people,
The number of people in the second workshop is (3 / 4) / (1 + 3 / 4) = 3 / 7 of the total number in the second workshop and the third workshop, that is, (3 / 7) * (3x / 4) = 9x / 2;
x/4+9x/28=320
16x=320*28
X = 560 (person)

A pair of rabbits can give birth to a pair of rabbits every month. A pair of rabbits can give birth to a pair of rabbits in the second month. How many pairs can a pair of rabbits breed in a year?
The logarithm of rabbits in the first nine months is: 1,2,3,5,8,13,21,24,55
