Answer:
x = 23 degrees
Because if you look at diagram x is vertical to angle FBC, and angle FEC and angle EBA are alternate interior angles so they are equal to each other, and AC is a straight line which means it equals to 180 degrees.

x = 23 degrees
A trick that is good for multiplying 9's is, remember that each time the tens digit changes the number in the ones spaces minuses 1. If you don't understand what I am saying look at the following:-
9
18
27
36
45
54
63
72
81
See the pattern? In the tens place you need to add 1 and in the tens place you need to subtract by 1.
