Answer:
72°
Step-by-step explanation:
Given
Zy = 108°
Zx = ?
We know
Zx + Zy = 180° {being supplementary angles }
Zx + 108° = 180°
Zx = 180° - 108°
Zx = 72°
Hope it will help :)
Multiply straight across (neg times a neg = a positive)
=28/81
B because m=slope and if the equation goes y=mx+b the only answer would be B <span />
