This is not exactly a GeoGebra request...

btw have a look at triangles BDA and BAC. They are similar (same angles), so the corresponding sides are proportional, e.g.

BD/AB = AB/BC

Solve this for BD and it's done.

As per U sir it is RIGHT AB^2=BD.BC


(3)^2=BD(5)

9/5=BD

BD=1.8

DE=2.6-1.8=.7

BUT SIR IT IS FIVE LINE

I WANT IN SECONDS IN ONE LINE.
