Answer:
[tex]x=15\ units[/tex]
Step-by-step explanation:
we know that
The Midpoint Theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side
so
In this problem
Applying the Midpoint theorem we have that
[tex]x=\frac{30}{2}=15\ units[/tex]
