Answer:
[tex]x=20.67\ ft[/tex]
Step-by-step explanation:
we know that
The Midpoint Theorem says 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
[tex]x=\frac{124}{3}:2=\frac{124}{6}=\frac{62}{3}=20.67\ ft[/tex]
