In the given figure, DE || BC.
(1) If AD 3.6 cm, AB = 9 cm and AE = 2.4 cm, find EC.
(ii) If
AD= 3/5
DB
and AC = 5.6 cm, find AE.
(iii) If AD = x cm, DB = (x - 2) cm, AE = (x + 2) cm
and EC = (x - 1) cm, find the value of x.
plz send me the answers

Step-by-step explanation:
Correct option is
A
3.6cm
Given: AD = 3.6 cm, AB = 9 cm and AE = 2.4 cm DE∥BC
Since, DE∥BC, by Equal Intercept Theorem,
BD
AD
=
EC
AE
AB−AD
AD
=
EC
AE
9−3.6
3.6
=
EC
2.4
EC=
3.6
2.4×5.4
EC=3.6 cm
