Question

Lista de exercícios teorema de Tales
1 nas figuras a//b//c, calcule o valor de x

Answer 1

Resposta:

V. 10/y = 3/6 = x/4

10/y = 1/2 = x/4

10/y = 1/2

y = 10 × 2

y = 20

x/4 = 1/2

2x = 1 × 4

2x = 4

x = 4/2

x = 2

VI. 10/(3x + 1) = 15/(5x - 2)

15(3x + 1) = 10(5x - 2)

45x + 15 = 50x - 20

-5x = -35

x = 35/5

x = 7
