if D and E are points on the sides AB and AC of a DeltaABC . Such that AB=12 cm, AD=8 cm, AE=12 cm, AC= 18 cm. show that DE||BC.

Let D, E be the points on sides AB and AC respectively of a triangle ABC such that DE is parallel to BC. Let AD = 2 cm, DB = 1 cm, AE = 3 cm and area of triangle ADE = 3 cm^2 What is EC equal to ?

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AE = 5 cm, AC= 7.5 cm, DE= 4.2 cm and DEabs() BC . Then find length of BC.

D and E are points on the sides AB and AC respectively of a triangle ABC such that DE||BC (i) If AD=3.6cm , AB=10cm and AE=4.5cm, find EC and AC . (ii) If AB=13.3cm , AC=11.9cm and EC=5.1cm, " find AD (iii) If (AD)/(DB)=(4)/(7) and AC=6.6cm find AE (iv) If (AD)/(AB)=(8)/(15) and EC=3.5cm find AE

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AD = 2 cm , BD = 3 cm , BC = 7.5 cm and DE || BC. Then length of DE (in cm) is (a) 2.5 (b) 3 (c) 5 (d) 6

In triangle ABC , D and E are points on the sides AB and AC, respectively, such that DE || BC. If AD = 5cm, DB = 9cm AE =4cm and BC = 15.4cm, then the sum of the length of DE and EC (in cm) is: triangle ABC में, D और E क्रमशः AB और AC भुजाओं पर बिंदु इस प्रकार है की DE||BC, यदि AD = 5cm, DB = 9cm AE = 4cm और BC = 15.4cm है, तो DE और EC (सेमी में) की लंबाई का योग है

In DeltaABC , D and E are points on sides AB and AC respectively such that DE||BC . If AE=1.8cm, BD= 7.2cm and CE= 5.4cm, then the length of AD is

In a triangle ABC, points D and E respectively lie on side AB and AC such that DE||BC . If AD=6cm, DB=(12x-6)cm, AE=2x cm and CE=16-2xcm then what is the value of x

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
