Pls help this homework is due tomorrow and I’m so confused thank you for taking your Time x

a)  x= 75

b) 105 is the same angle as angle B, I subtracted 180 by 105

180-105= 75

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
