what is the length of PR

Answer:
C) 6
Step-by-step explanation:
You can prove the 2 triangles are similar using AA similarity.
Because they are similar, their respective sides will be proportional.
You can write the proportion:
[tex]\frac{20}{24}=\frac{5}{x}[/tex]
where x = the length of side PR
Solve for x by cross-multiplying:
20x = 120
x = 6
