The length of EC will be 7.5 cm
Given DE || BC AD = 4cm, DB = 6cm, AE = 5cm
According to basic proportionality theorem- IF A LINE IS DRAWN PARALLEL TO ONE SIDE OF THE TRIANGLE INTERSECTING THE OTHER TWO SIDES, THEN IT DIVIDES IN THE SAME RATIO.
So,
In triangle ABC, DE || BC in the figure given below:
AD/AB = AE/AC……(1)
Now AB can be written as AD+DB similarly AC= AE+EC……(2)
Applying (2) in (1)
AD/AD+DB = AE/AE+EC……(3)
Applying values of AD,DB and AE from the question in equation (3)
4/(4+6) = 5/(5+EC)
4/10 = 5/(5+EC)
(10*5)/4 = 5+EC
EC = 7.5cm
