In the given triangle the lines are parallel.We can apply Triangle proportionality theorem.
The theorem states: If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
We can form a proportion using this theorem :
[tex] \frac{5}{3} =\frac{6}{x} [/tex]
To solve x we cross multiply:
5x=18
Dividing both sides by 5 we get
x=3.6
Second option.
