Ques. 1)

Solve In triangle ABC
DE||BC
AD = 2.5cm
DB = 3cm
AE = 3.75 cm
AC = ?

AD/DB = AE/EC [ By proportionality theorem ]

2.5/3 = 3.75/EC

EC = 3.75×3÷2.5

EC = 4.5 cm

AC = AE + EC

AC = 8.25 cm


Ques 2)

Solve In triangle ABC
DE || BC

AD/AB = AE/AC

1.7/6.8 = AE/9

AE = 9×1.7÷6.8

AE = 2.2 cm
