The value of x is 40.

Solution:

Given ΔVDG and ΔVNG are similar triangles.

DG = 207, NQ = 138, GQ = 60, QV = x

To find the value of x.

In two triangles are similar, then the measures of the corresponding sides are in proportional to each other.


$\Rightarrow(DG)/(NQ)=(GQ)/(QV)

Substitute the given values.


$ \Rightarrow(207)/(138)=(60)/(x)

Do cross multiplication, we get


$ \Rightarrow{207* x}=138*60


$ \Rightarrow{207* x}=8280

Divide by 207 on both sides of the equation, we get


$ \Rightarrow x=(8280)/(207)


$ \Rightarrow x=40

Hence the value of x is 40.
