Hii..
=> < DAB = 90° 【 Angle of square 】
=> < EAB = 60° 【 Angle of an equilateral ∆ 】
And , <DAE + < EAB = 90° 【 Angle of square 】
=> <DAE + 60° = 90°
=> <DAE = 90° - 60° = 30° answer.

WE KNOW THAT IN AN EQUILATERAL TRIANGLE ALL THE SIDES MEASURE 60 DEGREE THEREFORE /_EAB = 60 DEGREE
AND IN A SQUARE ALL THE ANGLE MEASURE 90 DEGREE
SO /_ DAB = 90 DEGREE
AND /_DAE = /_DAB - /_EAB
= 90 DEGREE - 60 DEGREE
= 30 DEGREE
