Angle AFE is supplementary to angle AFB because they are both along the line with points EFB. When two angles are along a straight line, they equal 180 degrees. This is also what the definition of supplementary is.

It’s angle AFE because its the one in the same line as AFB and since the line is 180 degrees that means they add up to 180
