This equals 49k-70
Hope this helped :)

Answer:
D.
Step-by-step explanation:
A) ∠V and ∠Y is not the alternate interior angles.
B)∠W and ∠Z is not the alternate interior angles.
C) Not this one because the reflexive property of congruence means that an angle, line segment, or shape is always congruent to itself.
D)∠VXW ≅∠ZXY because they are vertical. ∠W≅∠Y because they are right angles. So, triangles are similar by AA.
