Question

in a triangle ABC ,DE||BC and AD/BC=3/5if AC=4.8 find AE

Answer 1

Answer:

Step-by-step explanation:

hi friend

given

DE//BC,AD/DB =3/5 and AC=4•8cm

Since ABC is a triangle.

AB=AD+DB=3+5=8cm.

AC=4•8cm

So using Thales theorem,

AB/DB=AC/AE

8/3=4•8/AE

AE=4•8×3/8

= 0•6×3

=1•8cm

hope this helps
