Interesting, I come out to 55 degrees this way:

30 degrees between hours. 10 is at 300 degrees, 11 is 330 degrees. 50 minutes into the hour is 5/6 of 30 or 25. 330+25 == 355.

You're totally right, of course. I originally wrote 55 degrees (using exactly your argument) then looked at an actual clock and edited my post. Overthinking...
