Question

A pole 24 feet high has a shadow eight feet long. A nearby pole is 72 feet tall. How long is it's shadow?

Answer 1

What you have here are 2 similar triangles.

Therefore, since the corresponding sides are in the same proportion:-

24/72 = 8/h where h is the length of the tallest pole.

24h = 8*72

h = 8*72/24 = 24 feet answer
