Answer:
20°
Step-by-step explanation:
By inscribed angle theorem:
(Measure of inscribed angle is half of the measure of intercepted arc. )
To solve
replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)
so
I'm not sure if it is
![f(x)=\sqrt[3]{\frac{x}{7}}-9](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%7D%7B7%7D%7D-9)
or
![f(x)=\sqrt[3]{\frac{x}{7}-9}](https://tex.z-dn.net/?f=f%28x%29%3D%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%7D%7B7%7D-9%7D)
first one
replace f(x) with y
![y=\sqrt[3]{\frac{x}{7}}-9](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%7D%7B7%7D%7D-9)
switch x and y
![x=\sqrt[3]{\frac{y}{7}}-9](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B%5Cfrac%7By%7D%7B7%7D%7D-9)
solve for y
![x+9=\sqrt[3]{\frac{y}{7}}](https://tex.z-dn.net/?f=x%2B9%3D%5Csqrt%5B3%5D%7B%5Cfrac%7By%7D%7B7%7D%7D)
replace y with f⁻¹(x)
2nd one
replce f(x) with y
![y=\sqrt[3]{\frac{x}{7}-9}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%7D%7B7%7D-9%7D)
switch x and y
![x=\sqrt[3]{\frac{y}{7}-9}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B%5Cfrac%7By%7D%7B7%7D-9%7D)
solve for y
replace y with f⁻¹(x)
if you meant then the inverse is
