∆ABC is similar to ∆DEF. The measure of AB = 6, the measure of DE = 18, the measure of BC = 12, and the measure of DF = 15.

Find the measures of AC and EF.

AC =


_______________

EF =

Respuesta :

[tex] \frac{ab}{de} = \frac{bc}{ef} = \frac{ac}{df} [/tex]=k

[tex] \frac{6}{18} = \frac{12}{ef} [/tex]

[tex]ef = 36[/tex]

from this

[tex] \frac{12}{36} = \frac{ac}{15} [/tex]

[tex]ac = 5[/tex]

[tex] \frac{6}{18} = \frac{12}{36} = \frac{5}{15} = \frac{1}{3} [/tex]

I hope it helps
