Mary = (1/3)x
Erin = x - 8
John = x
Here is your equation:
(1/3)x + (x - 8) + x = 267
Take it from here.
Answer:
The height of the statue is <u>21.4 feet.</u>
Step-by-step explanation:
Given:
Distance of the person from the statue = 50 ft
Angle of elevation of the top of statue = 16°
Angle of depression of the bottom of statue = 8°
The diagram is drawn below.
In triangle ABC:
BC = 50 ft, ∠ABC = 16°
Using trigonometric formula;
![\tan(16)=\frac{y}{50}](https://tex.z-dn.net/?f=%5Ctan%2816%29%3D%5Cfrac%7By%7D%7B50%7D)
![y=50\tan(16)](https://tex.z-dn.net/?f=y%3D50%5Ctan%2816%29)
![y=14.337\ ft](https://tex.z-dn.net/?f=y%3D14.337%5C%20ft)
Now, let us determine the height of man, 'x'.
Consider triangle BDE.
ED = 50 ft, ∠BDE = 8°
Using trigonometric formula;
![\tan(8)=\frac{x}{50}\\\\x=50\tan(8)\\\\x=7.027\ ft](https://tex.z-dn.net/?f=%5Ctan%288%29%3D%5Cfrac%7Bx%7D%7B50%7D%5C%5C%5C%5Cx%3D50%5Ctan%288%29%5C%5C%5C%5Cx%3D7.027%5C%20ft)
Now, from the diagram, it is clear that, height of statue is given as:
![H=x+y=14.337+7.027=21.36\ ft\approx=21.4\ ft(Nearest\ tenth)](https://tex.z-dn.net/?f=H%3Dx%2By%3D14.337%2B7.027%3D21.36%5C%20ft%5Capprox%3D21.4%5C%20ft%28Nearest%5C%20tenth%29)
X+29/6=9
(convert mixed fraction to improper)
x=9-29/6
x=25/6 (calculate the difference)
therefore your answer is x=25/6
or x=4 1/6 OR x= 4.16
You just multiply the numbers to get 6.14448
