Question

PLease can someone help me, again?

Answer 1

Answer:

a = 55 (alternate angles)

123 + c = 180 ( linear pair or supplementary angles)

c = 180 -123 =57

c = 57

a + c + d = 180 (angle sum property)

55 + 57 + d = 180

112 + d = 180

d = 180 - 112

d = 68

c = b = 57 ( alternate angles)

b = 57

Answer 2

Answer:

123+55+x=180

178+x=180

a=2 d=55 c=123 b55
