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.
