Answer:
AC = 24
DE = 18
Explanation:
Assume that the given figure is a parallelogram. One of the properties of a parallelogram is that the diagonals bisect. This means that the following statements are true:
2 ( CE ) = AC
Substitute,
2 ( 12) = AC
24 = AC
(BD) / 2 = DE
Substitute,
(36)/2 = DE
18 = DE
