Answer 1

Answer:

a = 88°

b = 62°

c = 30°

d = 30°

Step-by-step explanation:

88° + c + 62° = 180°  (linear pair angles)

=> 150° + c = 180°

=> c = 30°

c = d   (vertically opposite angles)

=> d = 30°

a = 88°  (vertically opposite angles)

62° + c = d + b   (vertically opposite angles)

=> 62° + 30° = 30° + b

=> b = 92° - 30°

=> b = 62°
