Question

From a satellite 600 mi above the earth it is observed that the angle formed by the vertical and the line of

Answer 1

The angle at the satellite is 60.276 degrees, and the sine of this angle is 0.86842,

which from the dimensions of your triangle = R / (R + 600)

So R = 0.86842(R + 600),

from which you can, I'm sure, work out that,

R = 521.054 / 0.131576

which is = 3960

hope it helps!!
