Question

Please help me. I do NOT understand this.

Answer 1

Answer: 56 degrees.

Explanation:

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.

Answer 2

58

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
