Two angles are said to be supplementary if their sum is 180 degrees. So, if x and y are supplementary angles, the formula is

We know that one of the angles (say x) is 98. So, the equation updates to

If we want to solve for the other angle, we can simply subtract 98 from both sides to get

For this case we have the following exponential function:

Evaluating the function for x = -1 we have:

By power properties we can rewrite the function.
We have then:
Answer:
The value that completes the table when x = -1 is:
D. 2
Answer:
79 degrees
Step-by-step explanation:
180 - 101 = 79
Answer:

Step-by-step explanation:
The answer choices suggest there is a common factor of (x+2) that can be removed from numerator and denominator.
The denominator factors as ...

The numerator obviously has no factors of x. We can try any of several means to determine if (x+2) is a factor. I tried synthetic division and found that the numerator can be written as ...

Then the expression simplifies to ...
