Answer:
76.14 m
Step-by-step explanation:
create a proportion of height/shadow equals height/shadow
3.2/1.66 = h/39.5
cross-multiply:
1.66h = 39.5(3.2)
1.66h = 126.4
h = 76.14

If you have a part and a whole you can subtract the part from the whole to find the other part.
I'm not sure about it, but that's my best guess ;3
Good luck!
Answer:
9
Step-by-step explanation:
In the notation of a function f(x) = x+8, for input x=1 the output would be 9. And (1,9) would be an (x,y) pair that fits the function.
