Pouvez-vous m'aider svp c'est sur le théorème de Thalès et PPythagore : Exercice 1 :
Sur la figure ci-contre (qui n'est pas à l'échelle) :
E appartient à [AC],
D appartient à [BC],
CE = 7,3 cm ; CD = 4,8 cm ; DB = 0,96 cm.
Calculer AB.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
