Question

nos triângulos das figuras seguintes determine a medida X

Answer 1

Resposta:

a)

$\frac{x}{10} = \frac{12}{6} \\ 6x = 120 \\ x = \frac{120}{6} \\ x = 20$

b)

$\frac{2}{8} = \frac{3}{x} \\ 2x = 24 \\ x = \frac{24}{2} \\ x = 12$

c)

$\frac{4}{10} = \frac{x}{15} \\ 10x = 60 \\ x = \frac{60}{10} \\ x = 6$
