ПЕРИМЕТР РАВНОБЕДРЕННОГО ТРЕУГОЛЬНИКА РАВЕН 15,3 СМ ЕГО ОСНОВАНИЕ БОЛЬШЕ БОКОВОЙ СТОРОНЫ НА 3 СМ НАЙДИТЕ СТОРОНЫ ТРЕУГОЛЬНИКА

Answer 1

Ответ:

4,1 см,  4,1 см,  7,1 см

Объяснение:

Пусть боковые стороны по х см, тогда основание х+3 см.

х+х+х+3=15,3

3х+3=15,3

3х=12,3

х=4,1

Боковые стороны по 4,1 см,  основание 4,1+3=7,1 см

Answer 2

Perimeter of an Isosceles Triangle

To find the sides of an isosceles triangle when the perimeter is 15.3 cm and the base is 3 cm longer than the other side, we can use the following steps:

1. Let's assume that the two equal sides of the triangle are represented by x cm each. 2. The base of the triangle is 3 cm longer than the equal sides, so it can be represented as x + 3 cm. 3. The perimeter of the triangle is the sum of all three sides, which is given as 15.3 cm. 4. We can set up the equation: x + x + x + 3 = 15.3. 5. Simplifying the equation, we get: 3x + 3 = 15.3. 6. Subtracting 3 from both sides, we have: 3x = 12.3. 7. Dividing both sides by 3, we find: x = 4.1. 8. Therefore, the two equal sides of the triangle are 4.1 cm each, and the base is 7.1 cm (4.1 + 3).

So, the sides of the triangle are approximately 4.1 cm, 4.1 cm, and 7.1 cm.

Please note that these calculations are approximate due to rounding.
