A flagpole casts a shadow 15 feet long. Brad is 6 feet tall. If Brad casts a 4.5ft shadow, how tall is the flag pole?

Answer 1

6/4.5 = F/15

12/9 =F/15

12/3 =F/5

4=F/5

F = 20 feet tall for the flag pole

height = 4/3 times the length of the shadow

4.5 = 9/2 x 4/3 = 6 feet for Brad

15 x 4/3 = 20 feet for the pole
