The "trapezium" that I am refering to is a British one, meaning it is a quadrilateral with 2 parallel sides.

It depends what definition of trapezium you're using.
British trapezium: A quadrilateral with 2 sides parallel
USA trapezium: A quadrilateral with no sides parallel

A trapezium, by definition, has absolutely no sides parallel. Therefore, no unique solution exists. Perhaps you meant "trapezoid"?
This, it turns out, has a solution. Namely, the supplements of 78 degrees and of 123 degrees.

Let the other two angles be A and B.
then
0 < A < 159
and
B = 159 - A
