Question

перша сторона трикутника дорівнює 8 1/5 см дробь друга на 1 4/5 дробь см менше за першу сумма сторін на 3 4/5 дробь см більша за третю сторону чому дорівнює периметр трикутника​ ну хоть кто-то

Answer 1

Ответ:

8 1/5+1 4/5+3 4/5=13 4/5

Answer 2

Triangle Perimeter Calculation

To calculate the perimeter of a triangle, we need to know the lengths of all three sides. From the given information, we have:

- The first side of the triangle is 8 1/5 cm. - The second side is 1 4/5 cm less than the first side. - The sum of the sides is 3 4/5 cm more than the third side.

Let's denote the lengths of the sides as follows: - First side: a = 8 1/5 cm - Second side: b = (8 1/5) - (1 4/5) cm - Third side: c

We can use this information to calculate the perimeter of the triangle.

Calculating the Second Side

The second side is 1 4/5 cm less than the first side. We can calculate the length of the second side using this information.

The second side, b, can be calculated as: ``` b = a - 1 4/5 ```

Calculating the Third Side

The sum of the sides is 3 4/5 cm more than the third side. We can use this information to calculate the length of the third side.

The third side, c, can be calculated as: ``` a + b = c + 3 4/5 ```

Perimeter Calculation

The perimeter of the triangle is the sum of all three sides: ``` Perimeter = a + b + c ```

By substituting the calculated values of b and c into the perimeter formula, we can find the perimeter of the triangle.

Let's proceed with the calculations.
