Answer:
105°
Explanation:
A line equals 180, so take the two expressions and set them equal to 180:
x+82+x+112=180
simplify:
2x+194=180
2x=-14
x=-7
now plug the x value into the bolded expression
x+112
-7+112 = 105°
A - 105
since the two measurements are supplements, you do x+82+x+112=180. then you get x=-7. then you do 112-7=105
