Answer:
D (12).
Step-by-step explanation:
To find x, you would need to set up an equation. Since the whole angle, without the angle bisector, is 140, and one part of the angle with the bisector is 80, you would subtract 140-80, which would give you 60. Since the other angle is 5x, you would divide 60/5, which would give you 12, thus resulting in D as your answer.
