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)

Answer:
Inconsistent
Step-by-step explanation:
If a system has at least one solution, it is said to be <u>consistent</u>.
If a consistent system has exactly one solution, it is <u>independent</u>.
If a consistent system has an infinite number of solutions, it is <u>dependent</u>.
A system of equations is called an <u>inconsistent</u> system of equations if there is no solution.
Given the system of two equations

Add these two equations:

This is false statement, hence, the system of two equations has no solution and is inconsistent.


Use quadratic formula to solve (shown in picture):
We would get two answers:
x = .3808
and
x = -18.381
What? Can you try to rephrase it?!
