Answer:
D. 69°
Step-by-step explanation:
I think you divide 222° by 2, which equals 111, then subtract that from 180°, which equals 69°.
perp. : 1/3= m
y + 8 = 1/3(x -4): answer is c
y + 24/3 = (1/3)x - 4/3
y = (1/3)x - 28/3
answer is c
5x - 2 = (-9x) + 8
5x + 9x = 8 + 2
14 x = 10
x = 10 / 14
x = 5/7
