Salut!

Tu peux utiliser la loi des cosinus pour trouver la mesure du segment AB. Puis, tu peux utiliser un rapport trigonométrique (sin, cos ou tan) dans le triangle rectangle ACE pour trouver la mesure de la cathète CE.

Je te laisse essayer avec ces indices. Si tu as besoin d'aide supplémentaire, reviens nous voir! :)
