Answer 1

Answer:

b=50 a=50 c=130 d=50

Step-by-step explanation:

Answer 2

Answer:

A = 50°, B = 50°, C = 130°, D = 50°

Step-by-step explanation:

Let the 50° angle be E

D = E = 50° [Corresponding angle]

C = 180° - 50° = 130° [Linear pair]

B = E = 50° [Corresponding angle]

A = B = 50° [ Vertically opposite]

A = 50° , B = 50° , C = 130° , D = 50°
