Hello Tutor. I am having trouble with this problem on my precalculus homework. The topic is trigonometry. I have already tried to answer this question but continuously get it wrong. Can you show me how to solve?? The question has 3 parts to it and when you help me, I will post the 2nd and 3rd part in the comments area. As you can see from the provided photo, I can not progress to the next step until I correctly solve the first step. Can you show me? And then I will post a follow-up in the comments.
