Given:

The figure of a triangle.

To find:

The value of x.

Solution:

According to the triangle proportionality theorem, if a line segment divides the two sides of a triangle and parallel to the third side of the triangle, the it divides the two inclined sides proportionally.

Using triangle proportionality theorem, we get


(2x)/(80)=(27)/(60)


(x)/(40)=(9)/(20)

Multiply both sides by 40.


x=(9)/(20)* 40


x=9* 2


x=18

Therefore, the value of x is 18.
