The international space station orbits earth an altitude of about 240 miles. In the diagram the space station at point A. The radius of earth is approximately 3960 miles. To the nearest 10 miles what is EH, the distance from the space station to the horizon?

i believe a. 12x≥120 is the answer

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
