What is the additive identity of -9 ?

The additive identity of -9 would be 0

Step-by-step explanation:

The sum of any number with additive identity would end up being itself. So if two numbers are additive inverses, then they would add to give the sum of the additive identity (0).

Hope this helps you. Have a great rest of your day as well.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
