So the question ask to solve the said length of the triangle that has a value of 34in 20in and 47in and identify what kind of triangle is it. So by using the formula of pytagorean theorem , I came up with an answer of letter B. Obtuse. I hope you are satisfied with my answer and feel free to ask for more
Answer:
The angle of elevation is about 27°
Step-by-step explanation:
Let's view this case in the form of a right angled triangle. With the original height as the opposite side to the elevation angle and the shadow length as the adjacent side.
Let x represent the original height
2x is the length of shadow
And θ the angle of elevation
Applying trigonometry;
Tan θ = opposite/adjacent = original height/shadow length
Substituting the values;
Tan θ = x/2x
Tan θ = 1/2
θ = taninverse(1/2)
θ = 26.56505117707
θ ≈ 27°
Elevation angle is approximately 27°
96,083 ...add them together and divide by 3
