AC =AB + BC
16 = AB + BC

AB/BC=3/5=a  

AB=3a si BC=5a, 3a+5a=16 a=2 ,AB=2x3=6 cm si  BC=2x5=10cm
 

You are welcome!
Eu am raspuns primul , insa, am gresit la proportia derivata! Am folosit ca AB = 5k si BC = 3k; corect era ca AB = 3k si BC = 5k; mie imi dadu- se ca AB = 10 cm si BC = 6 cm; corect era AB = 6cm si BC = 10 cm. In rest, rezolvarea era in regula!
