Question

In ∆ABC, D and E are points on AB and AC respectively such that DE||BC, If AD/DB=3/4and AC= 15 cm, then what will be the value of AE .

Answer 1

hope it will help you:-)

Answer 2

AE Is to find

AD/DB. = 3/4

AD + DB = AB

3 + 4 = 7

by corolary of B.P.T

AD/AB = AE/AC

3/7 = AE/15

7 AE = 15 × 3

7 AE = 45

AE = 45/7

AE = 6.4CM
