Answer:
C
Step-by-step explanation:
[tex]\frac{C}{A} =\frac{hypotenuse}{shortest}[/tex] is the ratio of the hypotenuse of the largest triangle to that triangle's shortest side.
The ratio on the other side will relate corresponding sides.
So [tex]\frac{a}{?}=\frac{hypotenuse}{shortest}[/tex] where a is the hypotenuse of the smallest triangle. The shortest leg of this triangle is r.
