A)
acd = a + b
(Get the value of B from image)
136 = a + 56
(Subtract 56 from both sides)
136 - 56 = a
(Solve 136 - 56)
a = 80
(C is supplementary with 136)
136 + c = 180
(Subtract 136 from both sides)
c = 180 - 136
(Solve 180 - 136)
c = 44
Therefore:
a = 80 and c = 44
B)
egh = e + f
(Get values from image)
63 = e + 23
(Subtract 23 from both sides)
63 - 23 = e
(Solve 63 - 23)
e = 40
(G is supplementary with 63, supplementary angles equal 180
63 + g = 180
(Subtract 63 from both sides)
g = 180 - 63
(Solve 180 - 63)
g = 117
Therefore
e = 40 and g = 117
