Maths/Law of sines

I have a spherical triangle and I know 1 angle 31.3 degrees and all 3 sides which are 1624, 2118.4 and 1078.85 nautical miles.

In order to find the other 2 angles I know I must use the law of sines:

sin A over a = sin B over b = sin C over c

If angle A is 31.3 degrees and side a is 1078.85 nautical miles

Side b is 1624 and side c is 2118.4

I do have a scientific calculator but have no idea how to proceed

Please help

Mike

  1. You must use the fact that one degree around the earth is 60 nautical miles to get distances as angles.
