Ill assume it is :-
tan^2 A - 2 tan A + 1 = 0
(tan A - 1)^2 = 0
tan A = 1
m < A = 45, 225 degrees ( where 0 < m A < 360 )
1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
Hope this can help you.
