To solve the compound inequality \(-2 < 2x - 2 \leq 8\), we will break it down into two parts.
1. Solve the left inequality:
\[
-2 < 2x - 2
\]
Add 2 to both sides:
\[
0 < 2x
\]
Now, divide by 2:
\[
0 < x \quad \text{or} \quad x > 0
\]
2. Solve the right inequality:
\[
2x - 2 \leq 8
\]
Add 2 to both sides:
\[
2x \leq 10
\]
Now, divide by 2:
\[
x \leq 5
\]
Combining both parts, we have:
\[
0 < x \leq 5
\]
In interval notation, this is represented as:
\[
(0, 5]
\]
So, the correct choice is:
**A. The solution set is \((0, 5]\)**.
