Question

Qual a razão do segmento ab cd que medem
18cm e 2 raiz de 2cm

Answer 1

$\frac{AB}{CD} = \frac{18}{2 \sqrt{2} }$

$\frac{AB}{CD} = \frac{9}{ \sqrt{2} }$

Racionalizando :

$\frac{AB}{CD} = \frac{9}{ \sqrt{2} } . \frac{ \sqrt{2} }{ \sqrt[]{2} }$

$\frac{AB}{CD} = \frac{9 \sqrt{2} }{ \sqrt{2}. \sqrt{2} }$

$\frac{AB}{CD} = \frac{9 \sqrt{2} }{2}$
