Question

SOMEONE PLEASE HELP MEEEE

Answer 1

Answer:

$-180^{\circ}$

Step-by-step explanation:

Lines form 180 degrees on either side. The negative sign simply implies direction (clockwise instead of counter-clockwise), which is negligible as 180 is exactly half of 360 so you'd form the same line.
