Question

1.4 cm=AB

1.3 cm =BC

13 cm=CD

DE=Xcm
In the above figure, it pairs of triangles are similar, then find the
value of 'x'.​

Answer 1

DE = 14 cm , x = 14 if 1.4 cm=AB  ,  1.3 cm =BC  ,  13 cm=CD  pairs of triangles are similar

Step-by-step explanation:

ΔABC ≈ ΔEDC

=> AB/DE  = BC/CD  =  AC/CE

AB = 1.4 cm

BC = 1.3 cm

CD = 13 cm

DE = X cm

=> 1.4/X  = 1.3/13

=> 1.4/X = 0.1

=> 14/X = 1

=> X = 14

x  = 14

DE = 14 cm
