Question

Sabendo que r// s e s // t, caulcule o valor de x em centímetros

Answer 1

a)

$\frac{x}{3} = \frac{2,4}{2} \\ \frac{x}{3} = 1,2 \\ x = 3.1,2 \\ x = 3,6 \: cm$

b)

$\frac{x}{5} = \frac{2}{4} \\ \frac{x}{5 } = \frac{1}{2} \\ 2x = 5$

$x = \frac{5}{2} = 2,5 \: cm$

cl

$\frac{x}{4} = \frac{3}{6} \\ \frac{x}{4} = \frac{1}{2} \\ 2x = 4 \\ x = \frac{4}{2} = 2 \: cm$
