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!
