Question

calcule x e y sendo ABC ~ ABC

Answer 1

x/6 = 5/3
3x = 30
x = 10

y/6 = 4/3
3y = 24
y = 8

Answer 2

Teorema de Tales ... 

$\frac{AB}{CD} = \frac{EF}{GH}$     consiste na multiplicação cruzada. 

===========================================================

$\frac{3}{5} = \frac{6}{x} \\\\(multiplico\ cruzado)\\\\3.x=5.6\\\\3x=30\\\\x= \frac{30}{3} \\\\\boxed{\boxed{x=10}}$



=============================================================

$\frac{3}{4} = \frac{6}{y} \\\\(multiplico\ cruzado)\\\\3.y=4.6\\\\3y=24\\\\y= \frac{24}{3} \\\\\boxed{\boxed{y=8}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ok$
