Answer:
Step-by-step explanation:
Given is a function
![f(x) =(x-2)^2](https://tex.z-dn.net/?f=f%28x%29%20%3D%28x-2%29%5E2)
This function is a parabola with vertex at (2,0) and axis of symmetry is x=2
Hence for x<2 the curve would be reflection of x>2
To get inverse we must get one to one funciton only.
So restrict the domain of f(x) to ![[2,∞)](https://tex.z-dn.net/?f=%5B2%2C%E2%88%9E%29)
Then we have f(x) as one to one with domain x≥2 and range is R+
![f^{-1} (x)=+\sqrt{x} +2](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29%3D%2B%5Csqrt%7Bx%7D%20%2B2)
For this inverse domain is R+ and range is ![[2,∞)](https://tex.z-dn.net/?f=%5B2%2C%E2%88%9E%29)

The angle of elevation : α
tan α = 9/13
tan α = 0.6923
α = tan^(-1) 0.6923
α = 34.69° ≈ 35°
Answer: the angle is 35°
