Answer = 100°
The sum of a interior angles of a pentagon is 540°. So, if the 4 angles are 110°, this means that now the sum of the interior angles is 440°. Now, we just have to subtract 540° from 440°. Which is 100°.
BC is not a line. CF and BE are lines.

Answer:
angle 2 = 122
Step-by-step explanation:
we can substitute the angles for x and x+64
since they are supplementary, we know the some is 180
so we can form the equation x + x + 64 = 180
solve for x and we get 58
so angle 2 is 122
