Trying to get individual result wont be posible. Except you place some conditions necessary.
Triangles exist in so many forms, scalene, equilateral/equiangular, issocelles, then we talk about right-angles triange, obtuse-angled trinagle, acute angled triangle which are subgroup of the main group of "types of triangles"
Even if i give just one value of a triangle and accidentally or consiously denied to state the family in which such triangle belongs, then getting individual angles becomes imposible until i place some necessary even suffucient conditions on it.
