What do you mean "how many"? Like how many different rotations can you do and it'll be the same or just symmetries in general?
Two ways of solving it:
The angle beside the 71 is equal to
180 - 71 = 109
so a triangle angles sums up to 180
so the reminaing is
x = 180 - 109 - 28 = 43
solution (2):
the exterior angle = sum of interior angles except the one near it.
28 + x = 71
x = 43
