Answer:
x = 72
Step-by-step explanation:
If three or more parallel lines are intersected by two or more transversals, the parallel lines divide the transversals proportionally.
Given that the horizontal lines are parallel, then
[tex]\frac{x}{36}[/tex] = [tex]\frac{48}{24}[/tex] = 2 ( multiply both sides by 36 )
x = 72
