Answer:

CAB = 54

ABC = 21

ACB = 105

DCB = 75

Step-by-step explanation:

18x - 15 = (13x - 11) + (4x + 1)

18x - 15 = 17x - 10

x = 5

CAB = 13x - 11 = 13(5) - 11 = 65 - 11 = 54

ABC = 4x + 1 = 4(5) + 1 = 20 + 1 = 21

ACB = 180 - (CAB + ABC) = 180 - (54 + 21) = 180 - 75 = 105

DCB = 180 - ACB = 180 - 105 = 75
