Answer:

m<DEB=110

m<BCD=70

m<EAB=180-x-y=180+4+63=247

Step-by-step explanation:

For an isosceles trapezoid:

m<DEB≅m<EDC

x+114≅110

So

x=110-114=-4

Also m<DEB=114+x=114-4=110

m<EBC+m<DCB=180  property for Isosceles Trapezoid

m<EBC=180-110=70

m<EBC=133+y=70 So

y=70-133=-63

the answer is

m<DEB=110

m<BCD=70

m<EAB=180-x-y=180+4+63=247
