WebJul 16, 2024 · In this method calculating a single sine from scratch is not really anything you do -- it's not very much less work than creating the entire table, which is to say: years and years of painstaking manual calculations. See How to evaluate trigonometric functions by pen and paper? for a bit more detail. WebSo all we need to do is-- well we can simplify the left-hand side right over here. 65 plus 90 is 155. So angle W plus 155 degrees is equal to 180 degrees. And then we get angle W-- if we subtract 155 from both sides-- angle W is equal to 25 degrees. And we are done solving the right triangle shown below.
