Question

in ∆ABC, DE||BC if AD=4cm AB=18 cm then the length of AC is
​

Answer 1

Answer:

in ∆ABC

DE||BC

Step-by-step explanation:

we know that the theorem basic praportionality theorem that the ratio of corresponding sides are equal then ,

.

. . AD/AB =AE/AC

then, AD= 4cm and AB = 18cm

4/18=AE/AC

AE/AC = 2/9
