Explicação passo-a-passo:

Teorema de Tales :

1°)

$\frac{3}{12} = \frac{x}{16} \\ 12 \: . \: x = 3 \: . \: 16 \\ 12x = 48 \\ x = \frac{48}{12} \\ \red{ \boxed{x = 4}}</strong><strong>\</strong><strong>\</strong><strong>\</strong><strong>\</strong></p><p></p><p><strong>2</strong><strong>°</strong><strong>)</strong><strong>\</strong><strong>\</strong><strong>\</strong><strong>\</strong></p><p></p><p></p><p><strong> \frac{18}{9} = \frac{24}{x} \\ 18 \: . \: x = 9 \: . \: 24 \\ 18x = 216 \\ x = \frac{216}{18} \\ \red{ \boxed{x = 12}}$

3°)

$\frac{x}{8} = \frac{3}{4} \\ 4 \: . \: x = 8 \: . \: 3 \\ 4x = 24 \\ x = \frac{24}{4} \\ \red{ \boxed{x = 6}}$

4°)

$\frac{4}{10} = \frac{6}{x} \\ 4 \: . \: x = 10 \: . \: 6 \\ 4x = 60 \\ x = \frac{60}{4} \\ \red{ \boxed{x = 15}}$
