My guess would be the second choice - 90 degrees , I tried my best because idk if there’s a picture to this or anything :)
I believe it's 7.5 but I could be wrong.
Answer: 4
Step-by-step explanation: b =√c² - a ²
=√ 5² - 3 ²
=√16
=4
In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.
However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).
