24
Step-by-step explanation:
Statistically... this is just a permutation of 4
Check the picture below.
notice that the point A is the center of the circle, and thus the ∡BAF is a central angle, and the arc BF gets its angle measurement from ∡BAF, in red.
now, notice, ∡BAF has a twin
vertical angle, namely ∡CAE in green, and the arc made by ∡CAE is congruent to BF.

3a- 10° 3b- 55°
4a- 135° 4b- 45°
Complementary angles add up to 90°
Supplementary angles add up to 180°
