Answer:
Sorry for the late answer, but it seems like x = 92.
Explanation:
To try my best to find the length of x, I checked the other values to see if they fit into x.
- First, I tried 63 with 42, and while it was close, it was too large. This also rules out 63 with 50.
- Second, I tried 50 with 42, and it happened to fit.
I don't know what method you went for, but I used a program to work it out like a puzzle.
