Answer for arc AB:
since we know FB is the perpendicular bisector of AC then we know AB is the same length as BC so: 2x + 5 = 3x - 2 put everything on the left side
2x + 5 + 2 = 3x -2 + 2 2x + 7 = 3x put the variables on one side
2x - 2x + 7 = 3x - 2x 7 = x plug it in
2(7) + 5 = 19
AB = 19
Answer for segment DC:
since we know FB is the perpendicular bisector of AC then we know AD is the same as DC.
y + 8 = 5y put the variable on one side
y - y + 8 = 5y - y 8 = 4y simplify
8/4 = 4y/4
2 = y plug it in
5(2) = 10
DC = 10
