Answer:
SSS
Step-by-step explanation:
REM and DME share a side. This side is of course congruent.
In addition, sides RM and ED are marked as congruent, as are RE and MD.
All three corresponding sides of each triangle are congruent, which proves the triangles' congruency. 
No information is given about the angles in these triangles, so none of the other theorem answer choices are valid.
Please mark brainliest! :)

57 = -3d
Divide both sides by -3,
d = -19
