The construction makes ray BF a bisector of angle ABC. That bisector divides ABC into the two congruent angles DBF and EBF. As a consequence, angle EBF will be half of ABC, not equal to ABC.
Deandre = x Kala = x + 6 Eric = 3(x+6) x + x + 6 + 3(x+6) = 119 2x + 6 + 3x + 18 = 119 5x + 24 = 119 5x = 95, x = 19 Deandre has $19 Kala has 19 + 6 = $25 Eric has 3(25) = $75
