Question

In the given figure, the value of x for which DE || AB is

(a) 4
(b) 1
(c) 3
(d) 2

Answer 1

Given: In ∆ABC, DE || AB.

To find: the value of x

According to basic proportionality theorem if a line is drawn parallel to one side of a triangle intersecting the other two sides, then it divides the two sides in the same ratio.

In ∆ABC, DE || AB

x = 2

Hence we got the result .
