Answer: 117
Step-by-step explanation: Angle FAB is just 360 degrees minus all the other angles except 30. If you view the green/shaded area as a circle, there are 360 degrees, and FAB is a section of it. So 360-70-71-48-54=117. I hope this helps!
Answer:
117
add all and subtract from 360
Angle A is 87
meaning that to find angle FAB you need to add 30 and 87
And answer is 117
