Given:
Height of access ramp = 6 foot
Ramp ends at a point 40 feet away along the ground.
To find:
The angle of depression in nearest tenth of a degree.
Solution:
Using the given information, draw a figure as shown below.
In a right angle triangle,
![\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%20%3D%20%5Cdfrac%7B%5Ctext%7BPerpendicular%7D%7D%7B%5Ctext%7BBase%7D%7D)
In triangle ABC,
![\tan \theta=\dfrac{AB}{BC}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D%5Cdfrac%7BAB%7D%7BBC%7D)
![\tan \theta=\dfrac{6}{40}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D%5Cdfrac%7B6%7D%7B40%7D)
![\tan \theta=0.15](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D0.15)
Taking tan inverse on both sides.
![\theta=\tan^{-1}(0.15)](https://tex.z-dn.net/?f=%5Ctheta%3D%5Ctan%5E%7B-1%7D%280.15%29)
![\theta=8.5307656](https://tex.z-dn.net/?f=%5Ctheta%3D8.5307656)
![\theta \approx 8.5](https://tex.z-dn.net/?f=%5Ctheta%20%5Capprox%208.5)
Therefore, the angle of depression is 8.5 degrees.

Answer:
False, I think
Step-by-step explanation:
I’m not getting the full question but 4 cannot equal 23 so I would say false
1. <u>Plug in</u> " -2 " into f
f(-2) = 3 (-2) - 1
f(-2) = -6 - 1
f(-2) = -7
2. <u>Plug in</u> "5" into g
g(5) = -(5) + 6
g(5) = -5 + 6 = 1
3. <u>Add</u> what you got when you solved for <u>f(-2) and g(5) together</u>
f(-2) + g(5) = ?
f(-2) + g(5) = -7 + 1
f(-2) + g(5) = -6
Your answer is A
