Answer 1

x=11

Explanation:

12x + 2 and 2x + 112 are vertical angles meaning that they are equal to each other so we set up an equation that says 12x + 2 = 2x + 112 and solve for x

12x+2=2x+112

step one subtract 2 from each side

12x=2x+112

step 2 subtract 2x From each side

10x=110

step three divide each side by 10

x=11

Answer 2

x=11

Explanation:

12x+2 and 2x+112 are opposite exterior angles so they are congruent
