Answer 1

Ответ:

Периметр = 26см

Основа = 8см

две другие стороны равны между собой.= 26см

Решение

Две другие стороны = (26-8)/2 = 9

Ответ : 9

Answer 2

Perimeter of an Isosceles Triangle

To find the length of the remaining side of an isosceles triangle, we need to use the formula for the perimeter of a triangle. The perimeter of a triangle is the sum of the lengths of all its sides.

Given that the perimeter of the triangle is 26 cm and the length of the base is 8 cm, we can find the length of the remaining side.

Let's denote the length of the remaining side as x.

The formula for the perimeter of a triangle is:

Perimeter = Side 1 + Side 2 + Side 3

In this case, since the triangle is isosceles, Side 1 and Side 2 are equal, and Side 3 is the base.

So, we can write the equation as:

26 cm = x + x + 8 cm

Simplifying the equation, we have:

26 cm = 2x + 8 cm

Subtracting 8 cm from both sides of the equation, we get:

18 cm = 2x

Dividing both sides of the equation by 2, we find:

9 cm = x

Therefore, the length of the remaining side of the isosceles triangle is 9 cm.
