It seems like you're describing a scenario related to measuring the height of a tree using a specific distance. To find the height of a tree when you are standing a certain distance away, you can use basic trigonometry, specifically the tangent function.
If you have the angle of elevation from your position to the top of the tree, the formula is:
\[ \text{height} = \text{distance} \times \tan(\text{angle}) \]
Where:
- height = height of the tree
- distance = distance from the base of the tree (42 feet in your case)
- angle = angle of elevation to the top of the tree in degrees
If you can provide the angle of elevation, I can help you calculate the height of the tree. If you need help with something else related to tree height, just let me know!
