Answer:
ft
Step-by-step explanation:
Use the Pythagorean theorem to find the unknown side in any right triangle,
Essentially, look at it as if it was flat.
a is half of the diameter, so 2 ft.
b is your height, 9ft
![a^{2} +b^{2} =c^{2} \\2^{2} +9^{2} =c^{2} \\4+81= c^{2}\\\sqrt{85}=c](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5C2%5E%7B2%7D%20%2B9%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5C4%2B81%3D%20c%5E%7B2%7D%5C%5C%5Csqrt%7B85%7D%3Dc)
3(x + 4) = x/2 - 8
First, we can multiply both sides by 2:
6(x+4) = x - 16
6x + 24 = x - 16
Isolate x:
5x = -16 - 24
5x = -30
x = -6
