Answer:
58
Step-by-step explanation:
180=2x+8+x-2
180=3x+6 combine like terms
180-6=3x+6-6 isolate X
174=3x divde by 3 on both side
58=x
58-2=56
Answer: 56 degrees.
Angles on one side of a line add to 180.
To solve this, you can set both angles' sum to 180 to find x.
2x + 8 + x - 2 = 180
3x + 6 = 180
3x = 174
x = 58
58 - 2 = 56, that is the angle of DCB.
