The answer is that the probability that the last person ends in up in his proper seat is exactly
1
2
The reasoning goes as follows:

Answer:
a): A line has a total degree of 180. So just subtract it. 180-92 is

b): Similar to the previous, a right angle has a total angle of 90. 90-45=45.
y=45.
These are all the ones I can figure out. I hope someone else can get c) and d).
