Given in triangle ABC And triangle ADE BC || DE
Also AD/DB = 3/5,AC = 5.6

To find AE
In trinagle ABC And ADE
AD/BD = AE /EC. ----EQ 1........ ( By basic proportionality theorem....)

Doing reciprocal both sides we get
BD/AD = EC/AE

On adding 1 both sides we get,
BD + AD/AD = EC + AE/
= AB/AD = AC/AE
= 8/3 = 5.6/AE
= AE = 3 × 5.6/8
= AE = 2.1 cm Ans..

Hope it will be helpful
