Question

Периметр рівнобедреного трикутника АВС дорівнює 157 см , а основа 49 см ,. знайти інші сторони​

Answer 1

Ответ:

(157-49)÷2 = 108÷2 = 54 см - бічна сторона

Відповідь: інші сторони дорівнюють 54 см.

Answer 2

Perimeter of an Isosceles Triangle

To find the lengths of the other two sides of an isosceles triangle given its perimeter and base length, we can use the following formula:

Perimeter = 2 * Side Length + Base Length

In this case, we are given that the perimeter of the triangle ABC is 157 cm and the base length is 49 cm. Let's use the formula to find the lengths of the other two sides.

Perimeter = 2 * Side Length + Base Length

157 = 2 * Side Length + 49

To solve for the side length, we can rearrange the equation:

2 * Side Length = 157 - 49

2 * Side Length = 108

Side Length = 108 / 2

Side Length = 54 cm

Therefore, the lengths of the other two sides of the isosceles triangle ABC are both 54 cm.
