Answer:
<1 = <8
Step-by-step explanation:
An angle that will form a pair of alternate exterior angles with <1 will be the angle that is found outside of the parallel lines but on the opposite side of the transversal that cuts across the two parallel lines.
<8 is an exterior angle, and also is alternate angle to <1. It forms a pair of alternate exterior angles pair with <1.
Therefore, <1 = <8
