Answer: C

Step-by-step explanation:

C is a function because each of the inputs are distinct, meaning they only have one output each.

The other choices are not functions because at least one of the inputs corresponds to 2 or more outputs.

Hello there!

On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this : 

10x + 1 = 12x - 5
        -2x = -6
          x = 3

So the answer is x = 3.



In some problems, you have to find the angle.
Then you just simply substitute 3 into x.

10x + 1
10(3) + 1
30 + 1
31

12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.

Hope this helped! :)
