Question

2)In ∆ABC ,seg DE || seg BC ,A-D-B and A-E-C.If DB=5.1 ,AD=1.7 ,EC=7.5 then AE=___ *

22.5

0.25

25

2.5​

Answer 1

Step-by-step explanation:

In ∆ABC DE\\BC are given:

DRAW D on AB and E on AC.

AD/BD=AE/EC (By Thales Theorem)

1.7/5.1=AE/7.5 (BY CROSS MULTIPLICATION).

AE=1.7×7.5/5.1

Then, AE=2.5
