Explanation:
Some Properties of a Parallelogram
The opposite sides and angles are equal.
The adjacent angles are supplementary.
The diagonals of a parallelogram bisect each other.
Each diagonal separates it into two congruent triangles.
Here,
We can write
\(\angle DAC + \angle CAB = \angle DAB\)
or \(\angle x + \angle y = 50\) ( \(\angle CAB = \angle y\) ,The opposite sides and angles are equal)
We donot have much information, whether \(\angle x \) or \(\angle y\) is greater
Hence , Option D
