Answer:

x=58

m<ACD= 124°

Step-by-step explanation:

The sum of angles on a 180 angle should be 180 degrees.

2x+8+x-2=180

3x+6=180

3x=174

x=58

m<ACD= 2x+8= 2(58)+8= 124

Answer:

x=58°

m∠ACD = 124

Step-by-step explanation:

2x+8+x-2=180°  

- angles are supplementary which means they add together to equal 180, which is equivalent to a straight line.

3x+6=180°

3x=174°

x=58°

2(58)+8=116+8

m∠ACD=124°
