If somehow it can be proven that Triangle CEB is a 30-60-90 triangle, the answer can be found easily. However, it is confusing because the degrees are not given.

Is shape ABCD a square?
I think I could solve this using trigonometry.
Edit: nvm, I need at least some angles up in here

Okay so based on the answer choices given, I would have put 5 as the answer because the only Pythagorean triple I know that involves 4 is 3,4,5. Given this, CB is the hypotenuse and has to be 5 (based on this assumption). Assuming it is a square, CB is equal to AB so AB is 5
