Question

Calcule x, sabendo q EF//GH

Answer 1

Resposta:

$\frac{\frac{11}{2} }{2} = \frac{\frac{9}{4} }{x}$

multiplica cruzado

$\frac{9}{4} . 2 = \frac{11}{2} x$

$\frac{18}{2} = \frac{11x}{2} \\\\22x = 36\\x = \frac{36}{22} :(2) \\\\x = \frac{18}{11}$

ou

18/2 = 11x/2

9 = 11x/2

11x = 18

x=18/11
