Question 69048
A tree casts a shadow 27 meters long. A nearby post that is 5 meters tall casts a shadow 3 meters long. How tall is the tree?

Let x= height of tree

x is to 27 as 5 is to 3, or:

{{{x/27=5/3}}} multiply both sides by 27

{{{x(27/27)=5(27)/3}}}

{{{x=45}}}meters----------------------height of tree


Hope this helps----ptaylor
