Starla is 5feet 9inches tall. To find the height of a tree,she measured her shadow and the tree's shadow. Her shadow was 8feet long when the trees shadow was 30 feet long. To the nearest foot,how tall is the tree?

Let's set up a proportion and let x equal the height of the tree. Then cross multiply.
5.75/8 = x/30
8x = 172.5
x = 21.56 = 22 feet 
where did you get 5.75

5 ft., 9 inches = 5 9/12 = 5.75 feet

a lamppost cast a shadpw that is 24 feet ong. tad who is 6 feet tall is standing directly next to the lampost. his shadow is 15 feet long. about how tall is the lamppost?
