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

9514 1404 393
Answer:
x ≈ 0.309906932381 or 4
Step-by-step explanation:
There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.
Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.
