Answer 2

Finding the Sides of an Isosceles Triangle

To find the sides of an isosceles triangle, we need to use the given information that the perimeter of the triangle is 28 cm and it is larger than the sum of the two equal sides by 8 cm.

Let's assume that the two equal sides of the triangle are represented by the variable x. Since the triangle is isosceles, the third side will also be x.

According to the given information, the perimeter of the triangle is 28 cm. The perimeter of a triangle is the sum of all its sides. So we can write the equation:

x + x + x = 28

Simplifying the equation, we get:

3x = 28

Dividing both sides of the equation by 3, we find:

x = 28 / 3

Therefore, each equal side of the triangle is 28 / 3 cm.

Since the triangle is larger than the sum of the two equal sides by 8 cm, we can write another equation:

x + x + 8 = x

Simplifying the equation, we get:

2x + 8 = x

Subtracting x from both sides of the equation, we find:

x + 8 = 0

Subtracting 8 from both sides of the equation, we find:

x = -8

However, since we are dealing with lengths, the side of a triangle cannot be negative. Therefore, the value of x = -8 is not valid.

In conclusion, the sides of the isosceles triangle cannot be determined based on the given information.
