ABC est un triangle ; M est un point de [AB] et P un point de [AC]. On sait que les droites (BC) et (MP) sont parallèles.\\
De plus, on a : $\text{AP}=4$, $\text{AM}=5$ et $\text{AC}=6$.\\
Calculer AB.

\subsection{}
On sait que :\\
 $(MN) \parallel (BC)$ ; $AM = 1,6$ cm; $AC = 5$ cm ;\\ $AB = 4$ cm ; $BC = 6$ cm.\\
