Complete each statement:
Given: parallelogram QUAD with E as the point of intersection of the diagonals.
If CD = 16, then UA = ID.
If QU = 5, then AD = 5.
If the measure of angle UAD = 98, then the measure of angle ADO = 82.
If UA = ZAD and UA = 15, then AD = 15.
In short, not exact expression, but decimal.
