Explanation: In a parallelogram, diagonals bisect each other.
We are given that: BD and AC are diagonals of a parallelogram The two disgonals intersect at point E BE = 2x ED = x + 10
Now, based on the above, E bisects BD into two equal portions. This means that E is the midpoint of BD. Therefore: BE = ED 2x = x + 10 2x - x = 10 x = 10
We can check our solution: BE = 2(10) = 20 units ED = 10 + 10 = 20 units They are equal
