Aidez moi svp dm en maths ex 34

bonjour

EA/EL = EB/EG = AB/LG

x/ 5 = AB/10
5 AB = 10 x
AB = 2 x

EB/7 = 2 x / 10
10 EB = 14X
EB = 1.4 x

périmètre AEB = x + 1.4 x + 2 x = 4.4 x

thales

EA/EL = EB/EG = AB/LG
x/5 = AB/10
10x = 5AB
AB = 2x

EB/EG = AB/LG
ZB/7 = 2x/10
10EB = 14x
EB = 1,4x


P AEB = x+2x+1,4x =4,4x
