Question

in figure given below , DE parallel BC , if AB = 5.6 cm , AD = 2.6 cm , then find the AE ​

Answer 1

I hope it helps you Plz mark as a brain list plz plz plz plz plz plz plz plz plz plz plz

Step-by-step explanation:

AD=1/2BD, AB=3*AD.

∆les ABC & ADE are similar ∆ls,

as <A=<A,

<ADE=<ABC, and <AED=<ACB,

So, their sides must be proportional,

i.e. AD/AB =DE/BC

DE=BC*AD/AB=4.5*AD/3*AD=4.5*1/3=3/2=1.5 cm

DE=1.5 cm.
