Can you find betha3, s2 and s3 WITHOUT using the rule that the sum of angles of a triangle equals 180 degrees?

twice the sum of angles of a triangle equals 360 degrees.

How? Sine theorem doesn't work. Cosine theorem doesn't work too.

hmm maybe not. proving that the sum of interior angles is 180 degrees is incredibly trivial, though. restricting someone from not using that fact is pretty strange.

Why wouldn't sine law work? You get 3 linear equations in 3 unknowns from it.

Not quite.
