Answer:
![\theta=38.42 \textdegree](https://tex.z-dn.net/?f=%5Ctheta%3D38.42%20%5Ctextdegree)
Step-by-step explanation:
From the question we are told that:
Angle of F ![\angle F=90 \textdegree](https://tex.z-dn.net/?f=%5Cangle%20F%3D90%20%5Ctextdegree)
Length of ![EF = 2.3 feet,](https://tex.z-dn.net/?f=EF%20%3D%202.3%20feet%2C)
Length of ![FD= 2.9 feet,](https://tex.z-dn.net/?f=FD%3D%202.9%20feet%2C)
Generally the equation for Angle D
is mathematically given by
Since
.The triangle is a right angle Triangle
Therefore
![tan \theta=\frac{EF}{FD}](https://tex.z-dn.net/?f=tan%20%5Ctheta%3D%5Cfrac%7BEF%7D%7BFD%7D)
![tan \theta=\frac{2.3}{2.9}](https://tex.z-dn.net/?f=tan%20%5Ctheta%3D%5Cfrac%7B2.3%7D%7B2.9%7D)
![\theta=tan^{-1} 0.793](https://tex.z-dn.net/?f=%5Ctheta%3Dtan%5E%7B-1%7D%200.793)
![\theta=38.42 \textdegree](https://tex.z-dn.net/?f=%5Ctheta%3D38.42%20%5Ctextdegree)

Hey! Correct graph would be the second one. ( I attached the photo of it )
The answer is plan a : 170
Step-by-step explanation:
2. Amount of soil provided.
In order to give different pH values of the soil, the amount of soil can directly affect this independent variable.
