In triangle ABC shown below, AC = 14 km, AB = 28 km and angle ACB = 87 degrees. Select one of the following that can be used to find angle B

• $\frac{28}{Sin\ B}\ =\ \frac{14}{Sin\ \ 87}$

• $\frac{87}{Sin\ B}\ =\ \frac{14}{Sin\ \ 28}$
  

• $\frac{14}{Sin\ B}\ =\ \frac{28}{Sin\ \ 87}$
  

• $\frac{B}{Sin\ 28}\ =\ \frac{87}{Sin\ \ 14}$
