Tell how many triangles there are and solve each triangle completely

angle a equals 39.7 degrees angle c equals 91.6 degrees the length
of b equals 16.4

I solved it and got
---angle b=48.7 degrees
---a=13.9
---c=21.8

---Number of triangles -------I do not know------------
This is a ASA triangle so I am unsure how to determine how many triangles there are.
