Answer:
123°
Step-by-step explanation:
2z +9 = x
y = z
2Z +9 + X + z +Y = 360
Substitute for Z
2Z +9 + 2z +9 + z + z = 360
6z +18 = 360
6Z = 342
Z = 57
2(57) +9 = 123
X = 123
We first want to subtract 19 from both sides and lastly subtract 17 minus 19 and we get our answer.
19 + -2 = 17 is true and correct since if u add 19 plus negative two u can just do 19 minus two and still receive 17.
x = -2.
Yes maximum at it’s best because it is alway neutral
