Question

resolvas os teoremas de tales​

Answer 1

Resposta:

e)

$\frac{x}{x + 10} = \frac{4}{12}$

12x = 4 . ( x + 10)

12x = 4x + 40

12x - 4x = 40

8x = 40

x = 40/8

x = 5

g)

$\frac{6}{x} = \frac{4}{12}$

4x = 6.12

4x = 72

x = 72/4

x = 18

h)

$\frac{x}{9} = \frac{8}{4}$

4x = 8.9

4x = 72

x = 72/4

x = 18
