Non-right Triangles: Law of Sines · Exercise 13

Use the Law of Sines to solve for the missing side for each oblique triangle. Round each answer to the nearest hundredth. Assume that angle $A$ is opposite side $a,$ angle $B$ is opposite side $b,$ and angle $C$ is opposite side $c .$

Find side $c$ when $B = 37°, C = 21°,$ $b = 23.$
