Answer:
The correct answer would be D
Step-by-step explanation:
Triangles PQR and KLM are similar triangles, so their corresponding sides would be proportional. Side QR is correspondent to side LM, their ratio is 15:35 or 3:7, and apply that ratio to side PR to figure out X. [tex]\frac{72}{3}[/tex] is 24, 24 * 7 is 168, so the right answer would be D.
