Answer:

x=55

Step-by-step explanation:

Same side exterior angles are supplementary

x+9 and 2x+6 are same side exterior angles so they sum to 180

x+9 + 2x+6 = 180

Combine like terms

3x+15 = 180

Subtract 15 from each side

3x+15-15 = 180-15

3x= 165

Divide each side by 3

3x/3 = 165/3

x = 55
