Question

Наклоная крыша установлена на трех вертикальныз опорах основания которых расположены на одной прямой Средняя опора стоит посередине между малой и большой опорами высота малой опоры 2.2м высота большой опоры 2.7м найдите высоту средней опоры

Answer 1

1) 2.7 - 2.2 = 0.5 м - разность высот - по краям
2) 0,5 м : 2 = 0,25 -  разность высот до средней.
3) 2,2 + 0,25 = 2,45 м  или
3а)  2,7 - 0,25 = 2,45 м - ОТВЕТ

Answer 2

2,5-2,2=0,3 м разница между средней и большей опорами
2,2-0,3=1,9 м высота малой опоры
ответ: высота малолй опры равна 1,9 м

Answer 3

Calculation of the Height of the Middle Support

To find the height of the middle support, we can use the concept of similar triangles. Since the three supports are aligned in a straight line, we can consider the triangle formed by the heights of the supports as similar to the triangle formed by the distances between the supports.

Let's denote the height of the small support as h_small (2.2m) and the height of the large support as h_large (2.7m). We need to find the height of the middle support, which we'll denote as h_middle.

Using the concept of similar triangles, we can set up the following proportion:

h_small / (h_middle - h_small) = h_large / (h_large - h_middle)

We can solve this proportion to find the value of h_middle.

Let's substitute the given values into the proportion:

2.2 / (h_middle - 2.2) = 2.7 / (2.7 - h_middle)

Now, let's solve this equation to find the value of h_middle.

To solve the equation, we can cross-multiply:

2.2 * (2.7 - h_middle) = 2.7 * (h_middle - 2.2)

Expanding the equation:

5.94 - 2.2 * h_middle = 2.7 * h_middle - 5.94

Rearranging the equation:

2.2 * h_middle + 2.7 * h_middle = 5.94 + 5.94

Combining like terms:

4.9 * h_middle = 11.88

Dividing both sides by 4.9:

h_middle = 11.88 / 4.9

Calculating the value:

h_middle ≈ 2.4265

Therefore, the height of the middle support is approximately 2.4265 meters.
