Answer:
no the equation is not proportional and
x y
1 4
2 6
3 8
4 10
Step-by-step explanation:
Cos(x) = 1 at 0 and 2pi 360 and -360 is the same angle as 2pi so all of the above if you start at 0 and make a complete circle (360) you will be back at point 0.
Always- their slopes are always opposite reciprocals of each other
If you mean missing angle, it would be 129.
