However, the general formula for finding the midpoint
Let's assume you already know the coordinates of points N and H. Use the formula above, plug in the coordinates of N and H, and solve for
For example, if N has coordinates (a, b) and H has coordinates (c, d), then the midpoint M of NH can be calculated as:
Without the specific details from the image, I can only describe the process. Please use the coordinates provided in your image to find the midpoint.
