Question

ПЕРИМЕТР равнобедренного треугольника равен 28см а боковая сторона 10см НАЙДИТЕ ОСНОВАНИЕ ТРЕУГОЛЬНИКА

Answer 1

Если одна сторона равна 10 см и треугольник является равнобедренным→ вторая сторона равна тоже 10 см→ мы можем узнать третью сторону:
28-(10+10)=8 см
Ответ: основание равно 8 см.

Answer 2

В равнобедреного треугольника, боковые стороны равны.
Периметр –28 см, боковая сторона 10 см.
28 см - ( 10 см + 10 см) = 8 см.

Основание треугольника = 8 см.

Answer 3

Perimeter of an Isosceles Triangle

To find the base of an isosceles triangle when the perimeter is 28 cm and one of the sides is 10 cm, we can use the formula for the perimeter of an isosceles triangle.

The perimeter of an isosceles triangle is given by the formula: Perimeter = 2 * Side + Base.

Given that the perimeter is 28 cm and one of the sides is 10 cm, we can substitute these values into the formula and solve for the base.

Let's calculate the base using the given information:

Perimeter = 2 * Side + Base 28 cm = 2 * 10 cm + Base

To find the value of the base, we can rearrange the equation:

Base = Perimeter - 2 * Side Base = 28 cm - 2 * 10 cm Base = 28 cm - 20 cm Base = 8 cm

Therefore, the base of the isosceles triangle is 8 cm.

To find the base of an isosceles triangle when the perimeter is 28 cm and one of the sides is 10 cm, we can use the formula for the perimeter of an isosceles triangle.

The perimeter of an isosceles triangle is given by the formula:

Perimeter = 2 * side + base

Given that the perimeter is 28 cm and one of the sides is 10 cm, we can substitute these values into the formula and solve for the base.

Let's calculate the base:

Perimeter = 2 * side + base 28 cm = 2 * 10 cm + base 28 cm = 20 cm + base

To isolate the base, we subtract 20 cm from both sides of the equation:

28 cm - 20 cm = base 8 cm = base

Therefore, the base of the isosceles triangle is 8 cm.
