The transformed figure has the opposite orientation (A'B'C'D' is counterclockwise, whereas ABCD is clockwise), so a reflection is involved. The sgment C'D' is still at the bottom, as is CD, so the reflection must be across a vertical line.
In the attached, the light-blue figure A''B''C''D'' shows the reflection of ABCD across the y-axis. It is easy to see that figure A'B'C'D' is a translation of that 5 units downward.
The appropriate choice is the 2nd one ...
... Reflection over the y-axis followed by a translation down by 5 units.

Sum of all angles in a quadrilateral = 360°
Given :
▪︎Measure of angle U in quadrilateral RSTU = 80°
We know that corresponding angles in a quadrilateral are equal.
Which means :
▪︎Angle U = Angle y
Thus, the measure of angle y = 80°
Angle T = angle x (corresponding angles of a quadrilateral are equal)
Let us name angle T and angle x together as 2x.
Which means :
Thus, the measure of angle x = 100°
Therefore, the correct option is <em>(a) y = 80, x = 100</em>
