1. The problem statement, all variables and given/known data

A surveillance satellite circles Earht at a height of h miles above the surface. Suppose that d is the distance, in miles, on the sruface of Earth that can be observed fromt eh satellite. See the illustration.

(a) Find an equation that related the central angle theta to the height h

(b) Find an equation that relates the observable distance d and angle theta

(c) Find an equation that related d and h

(d) if d is to be 2500 miles, how high must the stellite orbit above Earth?

(e) If the stellite orbits at a height of 300 miles, what distance d on the surface can be observed?

2. Relevant equations

Trig ratios

3. The attempt at a solution

I have no idea were to even start there's not enough information or maybe my geometry just sucks because it has been a while sense i took that class.... I don't even know were to start

1. The problem statement, all variables and given/known data

Find the value of the angle theta in degrees rounded to the neartest tenth of a degree.
2. Relevant equations

trig ratios

3. The attempt at a solution

I have no idea how to even start this problem
