Question 22725
this is 2 similar triangles, so it is just simple ratio:


With ratio, i always tell my students to work in 3 stages:

1. write down what you know
2. Find what one is worth
3. Find what the Questions asks for.


I follow this method myself and i get the question correct. So, you decide if you want to learn my method...


1. I know 4foot shadow is from a 3foot (yardstick) stick
--> 4 from 3


2. so 1 from 3/4 (i got this just from dividing both sides by 4.)


3. so 47 from (3/4)*(47) --> i got this from multiplying both sides by 47
--> so 47 from 35.25feet


Height of the tree is 35.25 feet.
