Answer 2

Step-by-step explanation:

in the first fig. y is the vertical opposite to 80°

and hence y= 80°

and we know the sum of all angles= 180°

50°+80°+x= 180°

x= 180°-130°= 50°

in the second fig.

sum of all angles= 180°

y+50°+60°=180°

y= 180°-110°= 70°

x +y is a straight line= 180°

x+70°=180°

x= 180°-70°=110°
