Answer: The angle of elevation is 18.4 degrees (Approximately)
Step-by-step explanation: Please refer to the picture attached for more details.
The pole from top to bottom is 20 feet tall and is depicted as line FB. An observer is standing at a distance of 20 feet from the base of the pole, and that is depicted as line BA. The observer who is at point A looks up to the top of the flagpole at an angle of elevation shown as angle A.
Using angle A as the reference angle, line FB which is 20 feet would be the opposite (facing the reference angle), while line BA which is 60 feet would be the adjacent (that lies between the right angle and the reference angle).
Therefore, to calculate angle A;
Tan A = Opposite/Adjacent
Tan A = 20/60
Tan A = 1/3
Tan A = 0.3333
Checking with your calculator or table of values,
A = 18.4349°
Rounded to the nearest tenth,
A ≈ 18.4°
<u><em>Answer:</em></u>
The height of the stack = in
<u><em>Explanation:</em></u>
We are given that Jean stacks a dictionary on top of a novel.
This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.
<u>From the givens, we have:</u>
height of dictionary = in
height of novel = in
<u>Now, adding the two height, we will have:</u>
Total height of stack = height of novel + height of dictionary
Total height of stack = in
Hope this helps :)
