Determine the values of x and y so that quadrilateral ABCD is a parallelogram. ​

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
