Question

Периметр рівнобедреного трикутника дорівнює 60см. а бічна сторона - 12см. Знайдіть основу.

Answer 1

Ответ:

12+12=24 потом 60-24=36

Пошаговое объяснение:

12 две стороны т .к. у равнобедренного ∆ две стороны будут равны

Answer 2

Perimeter of an Isosceles Triangle

To find the base of an isosceles triangle when the perimeter and one of the equal sides are given, we can use the formula for the perimeter of a triangle and the properties of an isosceles triangle.

The perimeter of a triangle is given by the sum of all its sides. For an isosceles triangle with two equal sides (a) and one base (b), the perimeter (P) is calculated as:

P = 2a + b

Calculation

Given: - Perimeter (P) = 60 cm - One equal side (a) = 12 cm

We can use the formula to find the base (b): 60 = 2(12) + b

Solving for b: 60 = 24 + b b = 60 - 24 b = 36

Answer

The base of the isosceles triangle is 36 cm.
