In summary, the conversation discusses the need for help with spherical triangles and the various formulas that can be used to solve problems involving the lengths of sides and angles. The Haversine formula is mentioned as a potential solution, but the individual is unsure how to use it without knowing the values of a, b, and c. They also express frustration in finding examples to follow.

Look up Girard's theorem that should help you.

Girards formula gives me formulas for the area of a spherical triangle. Do I have to find the area in order to find the length of the sides? Do you know where I can see examples of solved problems like this. I can't find a single one.

I think you will find some examples in Wiki.

I for all of this formula all I really know is C for each formula. So if I have 50 degrees, do I write that the side opposite of that is:

cos(50) = (cos(a)cos(b) - cos(c))/(sin(a)sin(b))

I don't see how I can figure it out anymore than that not knowing what a b or c is? I'm so lost with this stuff!

A right spherical triangle is a triangle formed on the surface of a sphere, where one of the angles measures 90 degrees.

The three sides of a right spherical triangle are called the hypotenuse, the opposite, and the adjacent.

The length of the sides of a right spherical triangle can be found using the cosine, sine, and tangent functions, as well as the radius of the sphere and the given angles.

Yes, the Pythagorean theorem can be used to find the length of the sides of a right spherical triangle, just like it is used for right triangles in Euclidean geometry.

Yes, a right spherical triangle can have multiple solutions, as there can be more than one set of angles and sides that satisfy the given conditions.
