Question

Determine o valor de X nos feixes de retas paralelas.
(urgente, tô dando meu máximo de pontos, me ajudem por favor)​

Answer 1

              Proporcionalida

                             de  Segmentos

Uma vez que eles nos fornecem linhas paralelas, aplicamos Thales diretamente a cada um dos problemas:

Problema "e" :

$\dfrac{x}{5} =\dfrac{3}{6} \\\\\\6x=5(3)\\\\\\6x=15\\\\\\x=15:6\\\\\\\boxed{\bf{x=2,5}}$

Problema "f" :

$\dfrac{4}{2} =\dfrac{6}{x} \\\\\\4x=2(6)\\\\\\4x=12\\\\\\x=12:4\\\\\\\boxed{\bf{x=3}}$

Problema "g" :

$\dfrac{x}{6} =\dfrac{4}{4+8} \\\\\\\dfrac{x}{6} =\dfrac{4}{12} \\\\\\12x=6(4)\\\\\\12x=24\\\\\\x=24:12\\\\\\\boxed{\bf{x=2}}$

Problema "h" :

$\dfrac{x}{10} =\dfrac{2}{2+3} \\\\\\\dfrac{x}{10} =\dfrac{2}{5} \\\\\\5x=10(2)\\\\\\5x=20\\\\\\x=20:5\\\\\\\boxed{\bf{x=4}}$

Problema "i" :

$\dfrac{1}{1+4} =\dfrac{x}{5} \\\\\\\dfrac{1}{5} =\dfrac{x}{5} \\\\\\5(1)=5x\\\\\\\ \boxed{\bf{x=1}}$
