Answer:
x = 9 cm
Step-by-step explanation:
In triangle abc De is parallel to BC ad is equals to 2.5 cm DB equals to 5 cm AE is equals to 3 cm and ac is equals to X
DE || BC
=> AD / AB = AE/ AC
AD = 2.5 cm
AB = AD + DE = 2.5 + 5 = 7.5 cm
AE = 3 cm
AC = X
=> 2.5/7.5 = 3/X
=> 1/3 = 3/X
=> X = 3 * 3
=> X = 9
x = 9 cm
