Answer:
15 ft.
Step-by-step explanation:
I will assume that either both objects are standing straight. We can use similar triangles.
We can see that the side 8 is similar to the side 20, since they are both shadows. Therefore, we can set up an equation:
we can cross multiply and get:
8x=120
solve for x:
x=15
Therefore, the lamppost must be 15 feet tall (unless it fell down but we won't talk about that)

I hope this is good enough:
Answer: Solve for a: a = 
Solve for n: 
Step-by-step explanation:

solve for a: Divide each term in an = 9 + (n−1) ⋅ 8 by n and simplify.
