Answer:
C. ![\frac{8\sqrt{89}}{89}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%5Csqrt%7B89%7D%7D%7B89%7D%20)
Step-by-step explanation:
Cos A = Adj/Hyp
Reference angle = <A
Adjacent side = 8 ft
Hypotenuse = √(8² + 5²) = √89 (pythagorean theorem)
Thus:
![Cos (A) = \frac{8}{\sqrt{89}}](https://tex.z-dn.net/?f=%20Cos%20%28A%29%20%3D%20%5Cfrac%7B8%7D%7B%5Csqrt%7B89%7D%7D%20)
Rationalize
![Cos (A) = \frac{8 * \sqrt{89}}{\sqrt{89} * \sqrt{89}}](https://tex.z-dn.net/?f=%20Cos%20%28A%29%20%3D%20%5Cfrac%7B8%20%2A%20%5Csqrt%7B89%7D%7D%7B%5Csqrt%7B89%7D%20%2A%20%5Csqrt%7B89%7D%7D%20)
![Cos (A) = \frac{8\sqrt{89}}{89}](https://tex.z-dn.net/?f=%20Cos%20%28A%29%20%3D%20%5Cfrac%7B8%5Csqrt%7B89%7D%7D%7B89%7D%20)
Answer:
226.19 inches
Step-by-step explanation:
Y = mx + b
m = -2, b = 4
