Answer:
24 = AE
How to find it
AB = 26 and BD = 20 find AE
Because its a rhombus point is the midpoint of BD so BE is 1/2 BD so BE is 10
Now we no longer need to use BD and instead we use BE
Now since ∠BEA is 90° we can use the Pythagorean Theorem
AB²-BE²=AE²
26²-10²=AE²
676-100=AE²
576=AE²
=AE
24 = AE
