Question

could anyone tell me, what would be the error?​

Answer 1

Answer:

The question itself seems to be wrong. You cannot form a triangle with those values. But you could neglect one of the sides to get the value such that it forms a triangle.

If we consider side c is not given, then b & c will be 80.9 (both b & c are the same, i.e, isosceles triangle - Two angles are equal)

If we consider side a is not given and c is 100, then b would be 100 and a would be 61.8
