Points W and Z are reflections of each other in the x-axis. If W is the point (4,-3) what are the coordinates of Z?

(4,3)

Step-by-step explanation:

When you are flipping over the x-axis, you simply keep the x-coordinate the same and change the sign for the  y-coordinat

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
