Is there supposed to be a question or a picture with this ?
Answer:
Relative error = 0.0254 %
Step-by-step explanation:
Given details
Height of equipment from base is 104 ft
Elevation angle is 27.5 degree
From figure we have
.........1

x = 54.13 ft
differentiating 1st eq wrt x
![\frac{d}{dx} tan\theta = \frac{d}{dx} [\frac{x}{104}]](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%20tan%5Ctheta%20%3D%20%5Cfrac%7Bd%7D%7Bdx%7D%20%5B%5Cfrac%7Bx%7D%7B104%7D%5D)

Given:

Required:
To solve the given equation.
Explanation:
Consider

Divide 36 on both side, we get

Final Answer:
At those two x-intercepts, I know that x=2 and x=-2.
to get this, I know that there are two factors set to 0.
x+2=0 and x-2=0
so, if you multiply (x+2)(x-2)=y
then you will have standard form
x^2+2x-2x-4=y
y=x^2-4
