Question

Determine o valor de x nas figuras usando o teorema de Tales:


​

Answer 1

Resposta: a)  $\frac{4}{6}$ = $\frac{x}{18}$

6x= 4.18

6x= 72

x= $\frac{72}{6}$

x= 12

b) $\frac{3}{15}$ = $\frac{x}{10}$

15x= 3.10

15x= 30

x= $\frac{30}{15}$

x=2

2) a) $\frac{12}{8}$ = $\frac{3}{x}$

12x= 24

x= $\frac{24}{12}$

x= 2

b) $\frac{6}{10}$ = $\frac{x}{20}$

10x= 6.20

10x= 120

x= $\frac{120}{10}$

x= 12
