Answer 2

A dog, who is 8 meters from the base of a tree, spots a squirrel in the tree at an angle
of elevation of 40 degrees. What is the direct-line distance between the dog and the squirrel?

I suspect this is trigonometry?
I also hope you have learned about:
\[SOH = \sin \theta = \dfrac{Opposite}{Hypotenuse}\]
\[CAH = \cos \theta = \dfrac{Adjacent}{Hypotenuse}\]
\[TOA = \tan \theta = \dfrac{Opposite}{Adjacent}\]

The question gives us a triangle:
8 meters = Adjacent side.
40 degrees = \(\theta\)
