AoB = 35

BoC = CoD = X

DoE = BoC + CoD

EoF = 32

DoE = 2CoD ------------ DoE = BoC + CoD

DoE = 2X

 

Entonces :

AoB + BoC + CoD + DoE + EoF = 180

35 + X + X + 2X + 32 = 180

35 + 4X + 32 = 180

4X = 180 - 35 - 32

4X = 180 - 67

4X = 113

 

X = 113 / 4

AoD = AoB + BoC + CoD

AoD = 35 + 28,25 + 28,25

AoD = 91,5
