Answer:

x = 4

Explanation:

Given a line parallel to the side of a triangle and it intersects the other 2 sides then it divides those sides proportionally , that is


(BD)/(DA) =
(BE)/(EC) , substitute values


(x+2)/(x) =
(3)/(2) ( cross- multiply )

3x = 2(x + 2)

3x = 2x + 4 ( subtract 2x from both sides )

x = 4
