Answer:

C

Step-by-step explanation:

The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{PQ}[/tex] = [tex]\frac{AC}{PR}[/tex] , substitute values

[tex]\frac{20}{5}[/tex] = [tex]\frac{24}{PR}[/tex] ( cross- multiply )

20PR = 120 ( divide both sides by 20 )

PR = 6 → C
