Q5 of 95 Page 5

In the adjoining figure, DE || BC. Find x.

Given: AD = x

DB =16, AE = 34 and EC = 17


Given: DE || BC


Basic Proportionality theorem which states that if a line is drawn parallel to one side of a triangle the other two sides in distinct points, then the other two sides are divided in the same ratio.


So, by basic proportionality theorem





⇒ x = 32
