Answer 2

Answer:

Answer:A + B +C+ D=360'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'Now,

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'Now, D+ x=180'(Linear Pair)

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'Now, D+ x=180'(Linear Pair)140'+x=180'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'Now, D+ x=180'(Linear Pair)140'+x=180'x= 180'-140'

Answer:A + B +C+ D=360'90'+40'+90'+ D=360'(Property of quadrilateral.)220'+ D=360'D=360'-220'D= 140'Now, D+ x=180'(Linear Pair)140'+x=180'x= 180'-140'X= 40'
