Answer:
14
Step-by-step explanation:
So we know that triangle ABC and QRS are similar.
There is a theorem that states that corresponding sides of similar triangles are proportional.
This means that we can set up a proportion to find the missing side of the triangle.
3/7=6/n
Cross multiply.
3*n=7*6
3n=42
Divide both sides by 3.
n=14
