Tolong di jawab pakai cara

1). ACB = 180 – 108 = 72
BAC = 180 – 36 – 72 = 72
EBC = 180 – 36 = 144
2).Nilai X adalah 180 = 2x+5 + 57
180 = 2x + 62
180-62=2x
118 = 2x
118:2=x
59=x
ADC = 2 x 59 + 5 = 123
3). A = 180 -83 = 77
B = 115 karena bertolak belakang
C =180 – 75 = 105
D = 75 karena bertolak belakang
E = 180 – 75 = 105
F = 180 – 115 = 65
G = 65 karena bertolak belakang dengan F
4).CED = 180 – 112 = 68
CDE = 180 – 68 – 60 = 52
AEC = 112
AEB = 180 – 112 = 68
EAB = 180 – 68 – 60 =52
