Answer:
20
Step-by-step explanation:
The picture of the question in the attached figure
we know that
If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional
so
[tex]\frac{PQ}{AB}=\frac{PR}{AC}[/tex]
substitute the given values
[tex]\frac{y}{10}=\frac{28}{14}[/tex]
solve for y
[tex]y=10(2)\\y=20\ units[/tex]
