with Explaination all answer pls​

Answer 1

Answer:

A)- b = 120°(exterior alternative angles property)

a +b = 180°(linear pair property)

a= 180-b

a=180-120

a=60

B)85°+c =180°(co- interior angle property)

c=180-85

c=95°

c=d(vertically opposite angle property)

C)b +110°=180°(linear pair property)

180-110=b

70°=b
