Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) what is the measure of angle AFE

<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)
so

substitute the given values

Part 2) what is the measure of angle EFB?
we know that
---> by supplementary angles (form a linear pair)
so
substitute the given value
