Question 1186398: Rico and Jane are standing on a bike path looking at a tree, as shown in the diagram in the image. Jane is two times as far from the tree as Rico is. What is the approximate ratio of Jane’s distance from Rico to her distance from the tree? Here is a link to the image: https://imgur.com/a/GsdEXQD
I have the formula but I don’t know how to find cos^2 θ. This is the formula I have:
(1/2)^2 + cos^2 θ = 1
cos^2 θ = ?

Apparently you are given the required formula, so the image is irrelevant.

To find cos^2 θ, all you need to do is use the given equation.

%281%2F2%29%5E2%2Bcos%28theta%29%5E2=1
1%2F4%2Bcos%28theta%29%5E2=1
cos%28theta%29%5E2 = ___

It's simple arithmetic....
