Step-by-step explanation:
From the attached figure, AB is the height of the satellite and the distance between Ethan and the ground is 1 mile.
We can find the angle of elevation from Ethan to the satellite using trigonometry as follows :

So, the angle of elevation is 80.53 degrees.
diagonal is sqrt of (s^2 x 2)
8^2 = 64
64*2 = 128
sqrt(128) = 11.3137
