Answer 2

Step-by-step explanation:

a) x = 60° (opposite angle)

we know that,

60° + 40° + y = 180°

=> 100° + y = 180°

=> y = 180° - 100°

=> y = 80°

b) we know that,

x + 50° = 130°

=> x = 130° - 50°

=> x = 80°

and we know that,

y + 130° = 180°

=> y = 180° - 130°

=> y = 50°

hope it helps you!!
