【中学入試算数】小学，中学，高校の3つの解き方を解説！

This time, we've prepared a problem for finding length, specifically for junior high school entrance exam math. This problem explains three different solutions: one for elementary school, one for junior high, and one for high school. The junior high method uses the Pythagorean theorem, the high school method uses the Law of Cosines, and the elementary school method uses the relationship between adjacent side ratios, similarity ratios, and area ratios.
