Final answer:
The state located at 43 degrees North and 115 degrees West is Idaho, which is situated in the inland region of Western North America.
Step-by-step explanation:
The student has asked which state is located at 43 degrees North (N), and 115 degrees West (W). Looking at the given latitudes and longitudes for various regions, we can deduce that the location in question is in Western North America, particularly since the latitude is approximately in the middle of the ranges given for this region in multiple entries. The state matching the coordinates 43N and 115W is Idaho. None of the provided medians for longitude match exactly with 115W, which suggests that this point is inland rather than on the coast.
The closest median longitude given that encompasses Idaho in the entries is 123W, which is indicative of the western coastal region. By eliminating coastal states and states that are outside the 43N latitude, Idaho emerges as the correct answer since its capital, Boise, is near these coordinates.
