So the theorem is AIA but I can't find the value of x help please (oh and I thin the image is upsidedown.)

Answer:
x = - 6
Step-by-step explanation:
Remark
When parallel lines are cut by a transversal (as these lines are) then there are only 2 values for the angles can be made. In this case, the angles formed are alternate interior angles.
Alternate interior angles are equal.
Solution
x + 86 = 80 Subtract 86 from both sides.
x + 86-86 = 80 -86
x = - 6
