In the diagram, a ladder PS leaning against a vertical wall PR makes angle x° with the horizontal floor. The ladder slides down to a point QT such that angle QTR = 30° and SNT = y°. Find the relation between x and y.
- A. \(y = \frac{1}{2}x + 30\)
- B. \(y = \frac{1}{2}x + 30\)
- C. \(y = x + 30\)
- D. \(y = x - 30\)
Correct Answer: D. \(y = x - 30\)
