Answer 1

Resposta:

Utilizando o teorema de Tales:

$\\ \dfrac{6}{10} = \dfrac{3}{x} \\ \\ \bf \color{green} \: resolvendo: \\ \\ 6x = 30 \\ x = 30 \div 6 \\ \boxed{x = 5}$

Answer 2

$\large \boxed{ \begin{array}{l} \large \boxed{ \begin{array}{l}\boxed{ \rm{teorema \: de \: tales}} \\ \\ \rm{ \dfrac{6}{10} = \dfrac{3}{x} } \\ \\ \rm \: 6x = 10 \times 3 \\ \rm \: 6x \: = \: 30 \\ \rm \: x = 30/6 \\ \boxed{ \boxed{ \rm{x = \underline{5}}}}\end{array}}\end{array}}$
