Hello, I need help with finding the answer to this problem Suppose sin (theta) =5/13 and pi/2 is less than or equal to theta, which is less than or equal to pi, identify the values of x, y, and r. Show work for finding the missing value, find the value of cos(theta), find the value of tan(theta)

- I believe that y=5, since sin is (y/r), r= 13, and then using Pythagorean theorem x=12, and from there I can use the equation cos(x/r) to find cos, and then tan(y/x) to find tan

- The part I’m confused about is (since I got this wrong and the teacher didn’t give the solution, but did give us hints, and I want to understand how to solve it) is that x should be a negative value, so I don’t quite know how to progress, as I don’t understand what mistake I made. Thank you for your time
