1] OB = OD = 3 cm

2] AB / EF = BC / FG
5 / 15 = 6 / FG
FG = 6 x 15 / 5
FG = 18 cm

3] AO = √(AB² - OB²)
AO = √(5² - 3²)
AO = √(25 - 9)
AO = √16
AO = 4 cm

OC = √(BC² - OB²)
OC = √(6² - 3²)
OC = √(36 - 9)
OC = √27
OC = 3√3 cm

AC = AO + OC
AC = (4 + 3√3) cm
AC = 9,2 cm

AB / EF = AC / EG
5 / 15 = 9,2 / EG
EG = 15 x 9,2 / 5
EG = 27,6 cm
