Se considera triunghiul MNP si punctele R apartine (MN) SI Q apartine (NP) , astfel incat RQ || MP. Daca: RN = 4cm, MN = 10cm, NP = 15cm, calculati NQ! Help!!

[tex]\frac{NR}{NM}= \frac{NQ}{NP} \\\\ NQ = \frac{NP*RN}{MN}\\\\ NQ = \frac{15*4}{10} \\\\ NQ = \frac{60}{10} \\\\ NQ = 6 cm\\\\ MR = MN - RN \\\\ MR = 10 - 4 \\\\ \bold{MR = 6 cm}\\\\ QP = NP - NQ\\\\ QP = 15 - 6 \\\\ \bold{QP = 9 cm}[/tex]
