Answer:

[tex]120 = (15 + 22)x + 4 + 5 \\ 120 - 9 = 37x \\ 111 = 37x \\ x = 111 \div 37 = 3 \\ [/tex]

[tex]15x + 5 = 3 \times 15 + 5 = 50[/tex]

Answer:

Angle DCB = 60 degrees

Step-by-step explanation:

Line AD = 120

Angle D = 180 - 120 = 60

60 + 15x + 5 + 22x + 4 = 180

69 + 37x = 180

37x = 111

x = 3

15 ( 3 ) + 5 + 22 ( 3 ) + 4 + y = 180

45 + 5 + 66 + 4 + y = 180

50 + 70 + y = 180

120 + y = 180

y = 60
