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

The answer to the question
Answer:104
Step-by-step explanation:
104+75=180
3, 3*2+1, 7*2+1, 15*2+1, 31*2+1
3, 7, 15, 31, 63
You are adding a multiple of four
I believe it would be 24a^2-18ab.
