Question

Периметр треугольника АВС равен 62 см . ВС =17 см . АВ =СА. Найдите длину стороны АВ???

Answer 1

62-17=45
45÷2=22,5 AB и CA

Answer 2

(62-17)/2=22,5см - АВ и СА
Ответ: 22,5см

Answer 3

Perimeter of Triangle ABC

To find the length of side AB of triangle ABC, we need to use the information given about the perimeter and the lengths of the other sides.

The perimeter of a triangle is the sum of the lengths of all its sides. In this case, the perimeter of triangle ABC is given as 62 cm.

We are also given that side AC is equal to side AB, and the length of side BC is 17 cm.

To find the length of side AB, we can subtract the lengths of sides AC and BC from the perimeter of the triangle:

Perimeter of Triangle ABC = Length of AB + Length of AC + Length of BC

62 cm = Length of AB + Length of AC + 17 cm

Since Length of AC = Length of AB, we can substitute Length of AC with Length of AB:

62 cm = Length of AB + Length of AB + 17 cm

Combining like terms:

62 cm = 2 * Length of AB + 17 cm

Subtracting 17 cm from both sides:

45 cm = 2 * Length of AB

Dividing both sides by 2:

Length of AB = 22.5 cm

Therefore, the length of side AB of triangle ABC is 22.5 cm.
