We are given the opposite side (18) and the angle (33°), and we need to find the hypotenuse (y). Therefore we use sine:
\\(\sin(33^\circ) = \frac{18}{y}\\)
\\(y = \frac{18}{\sin(33^\circ)}\\)
\\(y \approx \frac{18}{0.5446}\\)
\\(y \approx 33.05\\)
Final Answer
\\(\boxed{1. \ x \approx 13.24, y \approx 17.57} \\)
\\(\boxed{2. \ y \approx 33.05}\\)
