Answer:

∠ ABC = 81° , ∠ FEC = 90°

Step-by-step explanation:

Since AB ≅ BC then Δ ABC is isosceles.

The median BE is therefore

The angle bisector of ∠ ABC and

BE bisects AC at right angles.

Thus

∠ ABE = ∠ CBE = 40° 30' , then

∠ ABC = 2 × 40° 30' = 81°

Since BE is perpendicular to AC then

∠ FEC = 90°
