No solution!

Explanation:

Assuming you need to use the Law of Sines to determine the answer, you are being asked to find the angle $B$ , its opposite side $b$ , the angle $C$ and its opposite side $c$ . The picture and formula for the Law of Sines is

Plugging in the givens, we have

$1/sin(124)=2/sin(B)$

Cross multiplying gets rid of the fractions.

$sin(B)=2xxsin(124)$

Using radians, we get

$sin(B)~~-1.99$

And using degrees, we get

$sin(B)~~1.66$

Unfortunately, neither of these answers is intelligible or coherent, because by definition, the $sin(B)$ must be between $-1$ and $1$ , that is:

$-1<=sin(B)<=1$
