Answer 1

Step-by-step explanation:

corresponding angles are equal

c = 100

b=d

Vertically opposite angles are equal

d = 100

so b = 100

b+x = 180

x = 180-100 = 80

x is corresponding angle to a

a=80

Answer 2

Step-by-step explanation:

d=100° because d is the vertically opposite angle of 100°

a=100° because it is the opposite angle of d

c=180°-100°=80°(adjacent angle of 100°)

b=80° b is the opposite angle of c
