Question

Периметр трикутника дорівнює 40 см. Чи може одна з його сторін дорівнювати 23 см?

Answer 1

Р=а+в+с
Я вважаю що ні адже 40-23=17 а 2 сторони в сумі мають більше число ніж 1 сторона

Answer 2

Не може тому що 23>17

Answer 3

Triangle Perimeter and Side Length

The perimeter of a triangle is the sum of the lengths of its three sides. In this case, the perimeter of the triangle is given as 40 cm. We want to determine if one of its sides can be 23 cm.

Calculation

To check if a triangle with a perimeter of 40 cm can have a side length of 23 cm, we can use the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Application of Triangle Inequality Theorem

Using the triangle inequality theorem, we can check if a triangle with a perimeter of 40 cm can have a side length of 23 cm: - Let's assume the side lengths of the triangle are a, b, and c. - According to the triangle inequality theorem, for a triangle to exist, the sum of the lengths of any two sides must be greater than the length of the third side.

So, for a triangle with a perimeter of 40 cm, it is possible for one of its sides to be 23 cm if the other two sides satisfy the triangle inequality theorem.

Conclusion

Based on the triangle inequality theorem, it is possible for a triangle with a perimeter of 40 cm to have a side length of 23 cm, as long as the other two sides satisfy the conditions of the triangle inequality theorem.

Therefore, it is possible for one of the sides of the triangle to be 23 cm.
