Question

3. If CE = 12, then AC = 4. If BD = 36, then DE =

Answer 1

Answer:

AC = 24

DE = 18

Step-by-step 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
