Question

Um triângulo tem seus lados medindo 3cm, 4cm e 5cm. Determine o comprimento dos lados de um triângulo semelhante, cujo perímetro mede 42cm.​

Answer 1

Resposta:

x = 14, y = 10,5 e z = 17,5

Explicação passo-a-passo:

**********************************************************************

x + y + z = 42

4 + 3 + 5 = 12

**********************************************************************

x/4 = 42/12

12x = 42 . 4

12x = 168

x = 168/12

x = 14

***********************************************************************

y/3 = 42/12

12y = 42  . 3

12y = 126

y = 126/12

y = 10,5

***********************************************************************

z/5 = 42/12

12z = 42 . 5

12z = 210

z = 210/12

z = 17,5
