#### Answer

There are no triangles which can be formed with the given parts.

#### Work Step by Step

We can use the law of sines to find the angle $B$:
$\frac{a}{sin~A} = \frac{b}{sin~B}$
$sin~B = \frac{b~sin~A}{a}$
$sin~B = \frac{(61)~sin~(58^{\circ})}{50}$
$sin~B = 1.0346$
Since there is no angle $B$ such that $sin~B \gt 1$, the angle $B$ is not defined.
There are no triangles which can be formed with the given parts.
