Dear Colleagues,

I have a non-special triangle with sides

a = 75mm, b = 67 mm, c = 117 mm.

I just want to calculate the angles alpha, beta, gamma using a/b =
sin[alpha]/sin[beta] &c. for a/c and b/c.

All my attempts with FindRoot, Solve, including prior TrigToExp
transformation were nugatory.

How?

Best regards,
