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'
