Students took the Similarity test (chapter 11) on Friday. This week we have learned the right-triangle definition of the trigonometric functions sine, cosine and tangent. As of now these functions take as input one of the non-right angles in a right triangle and their output is a specific ratio of sides in all such similar right triangles.
So, based on this definition, if that means that in any right triangle with a angle, the ratio of is approximately .57. In the figure below this means that .
