If ΔWXY is ≅ to ΔPQR, WX=5n-2 and PQ=63 what is n?

If the two triangles are congruent, then WX=PQ, because they are corresponding (by the order of the letters WXY and PQR). So if they are congruent, then we can say 5n-2=63, by the transitive property. The rest of the problem only requires Pemdas. Add 2 to both sides (5n=65), divide both sides by 5 (n=13), and you find that n=13.
