Only use that ACB and CED are congruent, not any other symbols in the diagram.
MHB Congruence of ACB & CED: Similarity Chapter

ACB and CED are confirmed to be congruent, while the term "similarity" is deemed unnecessary in this context. Triangle ABC is established as a right triangle, and although triangle CED's right angle status isn't explicitly stated, it is implied for the problem's validity. The congruence of angles ACB and CED leads to the conclusion that angles CAB and DCE are also congruent, resulting in angle ACE being a right angle. Consequently, triangle ACE is identified as a right triangle with legs measuring 7 and 24, allowing for the calculation of length AE using the Pythagorean theorem. This discussion emphasizes the importance of congruence in understanding the relationships between the triangles involved.

I don't think "similarity" is useful here (and the two triangles are definitely NOT "congruent". We are given that triangle ABC is a right triangle. (It is not specifically said that triangle CED is a right triangle but if angle CDE is not a right angle this problem is un-doable.) Angle ACB is congruent to angle CED. Since both triangles are right angles it follows that angles CAB and DCE are congruent and then that angle ACE is a right angle! So triangle ACE is a right triangle with legs of length 7 and 24. The length of AE follows from the Pythagorean theorem.
