right on. thats what i got well 122.88 degree. i needed to be a little more accurate.

0

sqrt (0) = 0^(1/2)

0 to any power is 0

here is a link to a diagram of the problem if anyone is still interested

Note: All I was given at the start of the problem was the swath coverage = 3000km (the curved area of the earth the satellite sees) and the altitude of the satellite = 830km.

I am trying to figure out the angle of a triangle with a curved base of 3000km it is part of a circle that has a circumference of 24902km and a radius of 6378km. There is a line that bisects the triangle. Its length is 830km. I need the angle of the triangle that is opposite the 3000km curved side. I wish I could add a picture it would make things easier. The triangle is outside the circle. Think of this problem as a satellite orbiting the earth.
