Solving Triangles (Ambiguous SSA case)

You can change the length of the rod by dragging the green dot at the end. You can also change the angle of the rod with the water by dragging the green dot at the reel or by pressing the -1 or +1.
The fishing rod is 2 m long and with angle of 30 degrees. Use the sine ratio to find the height of the end of the pole to the water. How many possible locations are there for fish if the fishing lines are of the following lengths? (Change the length of the line each time and drag the worm to see how many triangles can be made) (a) 1.2 m (b) 2.2 m (c) 1 m (d) 0.8 m
