Question

In ∆ABC, D and E are points on the sides AB and AC respectively such that DE || BC. If
AD = 4, AE = 8, DB = x – 4, and EC = 3x – 19, find x. If AD = 8cm, AB = 12 cm and
AE = 12 cm, find CE.

Answer 1

Answer:

11cm

Step-by-step explanation:

Given : AD=4 cm,DB=(x−4) cm,AE=8 cm and EC=(3x−19) cm.

To Find : x

We know that, by BPT(Basic proportionality theorem)

DB

AD

=

EC

AE

(x−4)

4

=

(3x−19)

8

4(3x−19)=8(x−4)

12x−76=8x−32

Solving, we get x=11 cm
