Answer 2

Step-by-step explanation:

Side DC is common to square and triangle.

it means side of square = side of triangle

DA=DE

In triangle ADE , angle ADE = 90+60 = 150

Angle DAE = Angle DEA

Sum of angles = 180

2 X angle DAE + 150 = 180

angle DAE = 15

And Triangle ADE is congruent to triangle BCE

So, AE= BE
