Answer:
C
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{PR}{MO}[/tex] = [tex]\frac{PQ}{MN}[/tex] , substitute values
[tex]\frac{x}{7.2}[/tex] = [tex]\frac{6}{10}[/tex] ( cross- multiply )
10x = 43.2 ( divide both sides by 10 )
x = 4.32 → C
