One ring in the Stonehenge Monument was originally made of 30 Stones, each about six and a half feet wide, 3 ft thick, and 13 ft

Answer:

46 units

Step-by-step explanation:

The diagonals of a rectangle intersect at their midpoints, indicating AE = EC. Therefore, set the equations equal and solve for x:

6x - 55 = 3x - 16

3x = 39

x = 13

Additionally, another characteristic of rectangle diagonals is their equal lengths, hence AC = DB. Now, let’s assess the length of AC:

AC = AE + EC = (6 * 13 - 55) + (3 * 13 - 16) = 23 + 23 = 46

Since AC = DB, it follows that DB = 46 units.

I hope this clarifies your question!
