Given rectangle ABCD with X as the midpoint of AB, we know that angles in a rectangle are right angles. Since CXD is given as 118 degrees, we can find angle ADX. Since angles around point X must sum to 360 degrees, we have ( \angle ADX = 180 - \angle CXD = 180 - 118 = 62 ) degrees. Consequently, since ( \angle XCD ) is supplementary to ( \angle ADX ), ( \angle XCD = 180 - 62 = 118 ) degrees.
To prove that polygon ABCD is not a rectangle, we can show that it does not have four right angles or that the lengths of opposite sides are not equal. Additionally, if we find that the diagonals of the polygon are not equal in length, that would also confirm it is not a rectangle. Any of these conditions being violated is sufficient to establish that ABCD is not a rectangle.

In rectangle ABCD, angle CBD is given as 47 degrees. Since opposite angles in a rectangle are equal and adjacent angles are supplementary, angle ABC (adjacent to CBD) would be 180 - 47 = 133 degrees. Therefore, if x represents the measure of angle CBD, then x = 47 degrees.
