The answer picture 4. So the first step is to figure out the sines and cosines of theta (along with their signs in perspective). The next step is to find the trigonometric functions based on the results of first step. Sine and cosine are defined according to the following convention, with the key lengths shown in green: The hypotenuse has unit length, the side adjacent to has length , and the side opposite has length.
