Answer:
x = 108
Step-by-step explanation:
added together, these angles equal 360.
x - 1 + x - 71 + 216 = 360
combine like terms
2x - 72 + 216 = 360
2x + 144 = 360
subtract 144 from both sides of the equation
2x + 144 -144 = 360 - 144
2x = 360 - 144
2x = 216
x = 216/2
Answer: -1 would be -d
0 -> d
1 -> f
2 -> stays same
(if this is not the right answer I'm sorry because i learned this awhile ago
y = -3x - 1
don't mind this hebusesjaygsnzoinske
i don't know
