to estimate the height of a tree, Dave stands in the shadow of the tree so that his shadow and the tree's shadow end at the same point. Dave is 6 feet 4 inches tall and his shadow is 15 feet long. If he is standing 66 feet away from the tree, what is the height of this tree?

See the last picture at the bottom of this web page (for a pic of this exact problem).

Using ratios,

Tree height = T

15/66 = 6.33/T

15T = 512.73

T = 34.182

T = 34.182
