Answer 1

It's 80 the pair of correspondence

Answer 2

1} angle ABY is 60 &angle y° is alternate angle so y = 60°.
then angle x & angle y is corresponding angle
x+y=180
x + 60 = 180
x = 180- 60
x = 120°
2} angle A = 80 then angle B is an alternate angle so, angle B is also 80 then angle x is opposite angle to angle B. angle x = 80°.
then angle A is alternate angle to angle ADC = 80°,then angle ADC & angle y =180
80 +y = 180
y = 180 - 80
y = 100°
