I need answers to a and b please ;D

Answer:
Angle x is 75 degrees because 180-105 = 75 so the angle next to 105 is the alternate exterior angle to angle x which means they are equal
Step-by-step explanation:
Answer:
a) 75 deg
b) see below
Step-by-step explanation:
a)
x + 105 = 180
x = 75
b) <x and <ABF are supplementary since they are a linear pair, so
x + m<ABF = 180
Since lines AD and EH are parallel, corresponding angles ABF and EFG are congruent.
m<ABF = m<EFG
x + m<EFG = 180
x + 105 = 180
x = 75
