Answer 2

Step-by-step explanation:

In △ABC, we have

       DE∣∣BC

⇒ ADAB=AEAC

Thus, in triangles ABC and ADE, we have

        ADAB=AEAC

and, ∠A=∠A

Therefore, by SAS-criterion of similarity, we have

      △ABC∼△ADE

⇒ ADAB=DEBC.......(i)

It is given that 

    ADAB=32

⇒ ADDB=23

⇒  ADDB+1=23+1

⇒ ADDB+AD=25

⇒  ADAB=25   .............(ii)

From (i) and (ii), we get

       DE
