Avery erects a radio antenna in his backyard. How many feet tall is the antenna?
Triangle ABC is similar to triangle RST.
\(\frac{BC}{AC} = \frac{ST}{RT}\)
6/5 = ST/40
ST = 48 feet.
The triangles are not congruent. The triangles are similar.

I'm glad you corrected your answer.
x is to 40 as 6 is to 5
x / 40 = 6 / 5
5 • x = 40 • 6
5x = 240
x = 48
