Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
This is a right angle triangle.
Suppose the angle from person to top of the tree is x
Using SOH CAH TOA
Tan x = [tex]\frac{opposite}{adjacent}[/tex]
Tan x = [tex]\frac{115}{70}[/tex]
Tan x = 1.6428
taking tan inverse
x = 58.67 degrees
Means the person need to look up 58.67 degrees. : Answer
