What angle measure is represented by the shaded part of the circle? Explain how you found your answer.

Quadrilateral wxyz was dilated with the origin as the center of dilation to create quadrilateral w'x'y'z'. the quadrilateral was dilated using a scale factor of 2. the coordinates of the vertices of quadrilateral wxyz are given. you can use the scale factor to find the coordinates of the dilated image. enter the coordinates of the vertices of quadrilateral w'x'y'z'
