Answer:

x = 14

Step-by-step explanation:

In the triangle O is the centroid.  

Now, we know that the centroid divides the medians in the 2 : 1 ratio that means the distance from the centroid to the vertex and the distance from the centroid to the opposite side remains in 2 : 1 ratio.

So, from the given diagram we can write  

[tex]\frac{3x}{2x - 7} = \frac{2}{1}[/tex]

⇒ 3x = 4x - 14

x = 14 (Answer)
