Question

ABCD is a square and ABE is an equilateral triangle on side AB of the square. Angle DAE measures.

Answer 1

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.

hope this helps :)

Answer 2

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
