Answer:
<8
Step-by-step explanation:
The alternate exterior angle property implies that the two angles must be an alternate exterior angles. Thus form the given diagram,
<3 = <6 (alternate interior angles)
<4 = <5 (alternate interior angles)
Therefore,
<1 = <8 (alternate exterior angles)
<2 = <7 (alternate exterior angles)
Thus, the angle that forms a pair of alternate exterior angle with angle 1 is angle 8.
