D and E are points on the sides AB and AC respectively of a `Delta ABC` such that `DE||BC`.
Find the value of x, when
(i) `AD =x cm, DB=(x-2) cm`,
`AE=(x+2) cm and EC =(x-1) cm`.
(ii) `AD=4 cm, DB =(x-4) cm, AE =8 cm`
and `EC=(3x-19) cm`.
`(iii) AD =(7x-4) cm, AE =(5x-2) cm, DB (3x+4) cm and EC= 3x cm`.

If D and E are points on the sides AB and AC respectively of a triangle ABC such that DE || BC. If AD =x cm, DB =(x-3) cm, AE = ( x+ 3 ) cm and EC = ( x -2) cm, what is the value (in cm. ) of x ?

If D and E are points on the sides AB and AC respectively of DetlaABC such that AB=5.6 cm, AD=1.4 cm, AC=7.2 cm and AE=1.8cm . Show that DE||BC .

In the figure if DE||AB, find the value of x . Given AD= (x-4). DC= 4cm, EB= (3x-19) cm and EC= (x-3) cm.

In the figure if DE||AB, find the value of x . Given AD= (x-4). DC= 4cm, EB= (3x-19) cm and EC= (x-3) cm.

In Delta ABC, DE||BC so that AD=(7x-4) cm, AE=(5x-2) cm, DB=(3x+4) cm and EC=3x . Then, we have

In Delta ABC , D and E are points in the sides AB and AC respectively such that DE || BC If AD = 6 cm , DB = 9 cm , and AE = 8 cm find AC.

D and E are points on the sides AB and AC respectively of Delta ABC . In each of the following cases, determine whetheer DE||BC or not. (i) AD=5.7 cm, DB =9.5 cm, Ae =4.8 cm and EC=8 cm . (ii) AB=11.7 cm, AC =11.2 cm , AD= 6.5cm and AE =41.2 cm , (iii) AB=10.8 cm, AD=6.3 cm, AC=9.6 cm and EC=4 cm . (iv) AD=7.2 cm AE=6.4 cm. AB =12 cm and AC=10 cm .

D and E are the points on the sides AB and AC respectively of a ABC such that: AD=8cm,quad DB=12cm,quad AE=6cm and CE=9cm. Prove that BC=5/2DE
