Question

ABCD is a square and ABE is an equilteral triangle on the side AB of the square DAE measure​

Answer 1

Step-by-step explanation:

as we all know that all the angles of an equilateral triangle is 60 and all angles of a square is 90

<DAB =90

<DAB=<DAE + <EAB

90 = <DAE + 60

<DAE= 90-60

<DAE=30
