WebTrigonometric ratios are not only useful for right triangles, but also for any other kind of triangle. In this unit, you will discover how to apply the sine, cosine, and tangent ratios, along with the laws of sines and cosines, to find all of the side lengths and all of the angle measures in any triangle with confidence. WebWhen we transform a sin x + b cos x = c into a sin x + b cos x = R sin ( x + k), we calculate the k angle by k = tan ( b / a). By using calculator, we get a positive or negative degree value for k.
