We are given a line segment $AB$, with various points defined as midpoints along this segment. The key idea is that each midpoint divides the segment it lies on into equal halves. We need to find the length of segment $GH$.

Let's break this down step by step.

1. Step 1: Interpret the Midpoints and Ratios

   • $C$ is the midpoint of $AB$, so $AC = CB = \frac{1}{2} AB$.
   • $D$ is the midpoint of $AC$, so $AD = DC = \frac{1}{2} AC = \frac{1}{4} AB$.
   • $E$ is the midpoint of $AD$, so $AE = ED = \frac{1}{2} AD = \frac{1}{8} AB$.
   • $F$ is the midpoint of $ED$, so $EF = FD = \frac{1}{2} ED = \frac{1}{16} AB$.
   • $G$ is the midpoint of $EF$, so $EG = GF = \frac{1}{2} EF = \frac{1}{32} AB$.
   • $H$ is the midpoint of $DB$, so $DH = HB = \frac{1}{2} DB = \frac{1}{2} \left(\frac{1}{2} AB\right) = \frac{1}{4} AB$.

2. Step 2: Use the Information Given We are told that $DC = 8$. From the breakdown above, $DC = \frac{1}{4} AB$.

   Therefore, we can find $AB$ as follows: $DC = \frac{1}{4} AB = 8$ $AB = 32$

3. Step 3: Find $GH$ Now, we need to find the length of $GH$, which spans from $G$ to $H$. The positions of $G$ and $H$ are fractions of the total length $AB$:

   • $G$ is $\frac{1}{32} AB$ from $A$,
   • $H$ is $\frac{3}{4} AB$ from $A$, since $H$ is the midpoint of $DB$, and $DB = \frac{1}{2} AB$, so $DH = \frac{1}{4} AB$.

   The distance $GH$ is the difference between these two positions: $GH = H - G = \frac{3}{4} AB - \frac{1}{32} AB$ To compute this, we first convert to a common denominator: $GH = \left(\frac{24}{32} - \frac{1}{32}\right) AB = \frac{23}{32} AB$ Now substitute $AB = 32$: $GH = \frac{23}{32} \times 32 = 23$

Thus, the length of $GH$ is $\boxed{23}$.
