There are so many ways to get this answer. Angle seven and 5 are vertically opposite so they're equal. Angles 4 and 5 are co-interior so they add up to 180°. If 180 is the total of 4+5, and 5 is 114 then 4 = 180-114 which is 66.
Angles 7 and 3 are corresponding and corresponding angles are the same. 3 and 4 are on a straight line so they add up to 180. 180-114= 66
