Question

Utilizando Teorema de Tales, resolva as seguintes questões:

Answer 1

Explicação passo-a-passo:

a) 2/4 = 3/X

2x = 12

x = 12/2

x = 6

b) 4/12 = x/21

12x = 4.21

12x = 84

x = 84/12

x= 7

c) x/14 = 9/12

12x = 14.9

12x = 126

x = 126/12

x = 63/6

d) x/9 = 8/12

12x = 9.8

12x = 72

x = 72/12

x = 6
