Question

Периметр треугольника 44 см. Одна из его сторон на 4 см меньше другой и в 2 раза больше третей стороны. Найдите стороны треугольника.

Answer 1

Пусть х одна сторона, тогда вторая (х+4), третья 2х, составляем уравнение х+ х+4+2х=44

4х=40

х= 10

10; 14; 20

Answer 2

I can help you with your math problem. Let me translate your question first.

You asked: Answer in detail. The perimeter of a triangle is 44 cm. One of its sides is 4 cm less than the other and twice as large as the third side. Find the sides of the triangle.

To solve this problem, we need to use algebra. Let x be the length of the third side, then the other two sides are 2x and 2x - 4. The perimeter is the sum of the three sides, so we have:

$$x + 2x + 2x - 4 = 44$$

Simplifying and solving for x, we get:

$$5x = 48$$ $$x = \frac{48}{5}$$

Therefore, the sides of the triangle are:

$$x = \frac{48}{5} \text{ cm}$$ $$2x = \frac{96}{5} \text{ cm}$$ $$2x - 4 = \frac{76}{5} \text{ cm}$$

You can check your answer by adding the three sides and verifying that they equal 44 cm.
