Answer:

Angle FAB = 75°

Step-by-step explanation:

13x - 3 = 3x + 2 + 55° ( Exterior angle of a triangle equal the sum of the two opposite interior angles)

13x - 3x = 57 + 3 = 60

10x = 60°

Divide both sides by 10

x = 6

Therefore,

Angle FAB = 13x - 3 = 13(6) - 3 = 78 - 3 = 75°

Angle FAB = 75°
