Question

Знайдіть сторони рівнобедреного трикутника якщо його периметр дорівнює 2 см причому бічна сторона на 2 см менша основи.Срочно.

Answer 1

пусть боковая сторона х,тогда основа 2+х

(2+х)+х=20

2+2х=20

2х=20-2

2х=18

х=9-боковая сторона => вторая сторона тоже 9

а основа 9+2=11

Answer 2

Finding the Sides of an Isosceles Triangle

To find the sides of an isosceles triangle when its perimeter is 2 cm and one of the sides is 2 cm less than the base, we can use the following approach:

Let's denote the base of the isosceles triangle as b and the two equal sides as a. The perimeter of the triangle is given by the sum of all its sides, which is:

Perimeter = 2a + b

Given that the perimeter is 2 cm and one of the sides is 2 cm less than the base, we can express the base in terms of the side length:

b = a + 2

Substitute this expression for b into the perimeter formula:

2a + (a + 2) = 2

Solving for a will give us the length of the equal sides, and then we can find the base length using the relationship b = a + 2.

Let's calculate the values using the given information.

Calculation

Substitute the expression for b into the perimeter formula:

2a + (a + 2) = 2

Combine like terms:

3a + 2 = 2

Subtract 2 from both sides:

3a = 0

Divide by 3:

a = 0

Conclusion

The calculation results in a = 0. However, this result doesn't seem to align with the given information and the nature of the problem. It's possible that there might be a mistake in the given information or the problem statement. Please double-check the values and the problem statement to ensure accuracy.
