Plz trapezoid w′x′y′z′ is the image of trapezoid wxyz under a dilation through point c. what scale factor was used in the dilation? a) -7/3 b) −3/7 c) 3/7 d) 7/3

50 % is the answer !

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
