The temperature would be about 54.
Well, the triangle could have a few possibilities to get the angles. They are:
30-30-120
30-60-90
30-90-60
30-120-30
60-30-90
60-60-60
60-90-30
90-30-60
90-60-30
Thus, there are 9 possible cases. Out of them 3 are good, so the probability is 1/3, or 33%.
To get f(h(x)), we simply plug h(x) into the x value(s) of f(x), resulting in
2(x²+1)-1=2x²+2-1=2x²+1
For g(f(x)), we plug f(x) into the x value(s) of g(x), resulting in
3(2x-1)=6x-3
The answer is yes because 1/2 is equal to 4/8 so 4/8 is bigger than 1/8 :))
i hope this is helpful
have a nice day
