answer: 121.5° i think???

explanation: since CE is parallel to BA, you can use the “F” pattern in order to prove that angle C is the same as angle EDA.
With this being 63°, you now have one angle inside of the triangle. Since all angles in a triangle add up to 180° and lines DE and AE are equal, we can call this an isosceles triangle. Therefore 180° - 63° = 117°.

With this, you can divide 117° by 2, because in an isosceles triangle, two angles are the same, and are left with 58.5° each.

To find angle BAE, you have to add 58.5° with the remaining portion of the angle, which you can find by using a “Z” pattern with the parallel lines CE and BA. Therefore, angle EAB is also 63°

Final step is to add 58.8° to 63°, which gives you angle BAE: 121.5°
