Question

Визнач вид трикутника,якщо одна з його з його сторін дорівнює 30 см,інша - 40 см,а периметр - 110 см.​

Answer 1

Рівнобедрений трикутник, оскільки Р трик.=110см то 30+40=70
110-70=40
Дві сторони по 40см і це означає, що трикутник рівнобедрений за двома сторонами

Answer 2

Triangle Type Calculation

To determine the type of triangle, given that one of its sides is 30 cm, another is 40 cm, and the perimeter is 110 cm, we can use the information provided to identify the triangle type.

First, let's calculate the length of the third side using the given perimeter and the lengths of the other two sides.

The perimeter of a triangle is the sum of the lengths of its three sides. Therefore, we can use the formula:

Perimeter = side1 + side2 + side3

Substituting the given values: 110 cm = 30 cm + 40 cm + side3 110 cm = 70 cm + side3 side3 = 110 cm - 70 cm side3 = 40 cm

Now that we have the lengths of all three sides, we can determine the type of triangle based on these lengths.

Triangle Type

The type of triangle can be determined based on the lengths of its sides. In this case: - If all three sides are of different lengths, it is a scalene triangle. - If two sides are of the same length, it is an isosceles triangle. - If all three sides are of the same length, it is an equilateral triangle.

Given that the lengths of the sides are 30 cm, 40 cm, and 40 cm, we can conclude that the triangle is an isosceles triangle.

This determination is based on the mathematical properties of triangles and the given lengths of the sides.
