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.
Welp I don't like Geometry xd Sorry but I am really good at Algebra, not Geometry @AshyNashy are you good at geometry?
Is shape ABCD a square? I think I could solve this using trigonometry. Edit: nvm, I need at least some angles up in here
Are you sure there isn't any more given information? I don't think it's solvable without any other given info
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
