Answer 1

Answer:

c=180-123=57

b=57

a=57

d=57+55=112

180-112=68

Step-by-step explanation:

Answer 2

Answer:

a = 55°

b = 57°

c = 57°

d = 68°

Step-by-step explanation:

=> 123° + c = 180° (Linear pair of angles)

=> c = 180° - 123°

=> c = 57°

=> c = b (Alternate interior angles)

=> 57° = b

=> a = 55° (Alternate interior angles)

=> a + c + d = 180° (Angle sum property of

triangles)

=> 55° + 57° + d = 180°

=> 112° + d = 180°

=> d = 180° - 112°

=> d = 68°
