Răspuns:
a. AM=15cm; BC=36/5=7,2cm
b. AM=20/3=6,(6)cm; BC=54/5=10,8cm
Explicație pas cu pas:
a.
[tex] \frac{am}{ac} = \frac{an}{ab} = \frac{mn}{bc} \\ \frac{am}{9} = \frac{10}{6} = \frac{12}{bc} \\ am = 15 \\ bc = \frac{36}{5} [/tex]
b.
[tex] \frac{ab}{am} = \frac{ac}{an} = \frac{bc}{mn} \\ \frac{6}{am} = \frac{9}{10} = \frac{bc}{12} \\ am = \frac{20}{3} \\ bc = \frac{54}{5} [/tex]
