Question

ajutati maaaa ex 8.......​

Answer 1

Explicație pas cu pas:

a)

$\dfrac{MD}{MA} = \dfrac{8}{24} = \dfrac{1}{3}$

$\dfrac{ME}{MB} = \dfrac{1}{3}$

=> DE || AB

b)

din a) => ΔMDE ~ ΔMAB

=>

$\dfrac{MD}{MA} = \dfrac{DE}{AB} \iff \dfrac{1}{3} = \dfrac{DE}{30}$

$DE = \dfrac{30}{3} \implies DE = 10 \ cm$
