Периметр треугольника равен 16 см.Две его стороны равны между собой,и каждая из них на 2,9см больше чем третьей.Каковы стороны треугольника?

To find the sides of a triangle, we can use the formula: sides = perimeter / 3

In this case, the perimeter is 16 cm. So, each side of the triangle would be: sides = 16 cm / 3 = 5.33 cm

Since two of the sides are equal, each side would be: 5.33 cm + 2.9 cm = 8.23 cm

Therefore, the sides of the triangle are 8.23 cm, 8.23 cm, and 5.33 cm.
