By L Camarota

Use either the Law of Sines or the Law of Cosines along with the information given to find the missing angle or side requested.

side a = 5 m, side b = 4 m, angle A = 30°, angle B = ?

side a = 4 m, side b = 3 m, angle C = 50°, c = ?

side b = 10 m, angle B = 50°, angle C = 90°, c = ?

a = 4 m, b = 5 m, c = 6 m, angle C = ?

a = 3 m, b = 4 m, angle A = 37°, angle C = ?

a = 10 m, b = 9 m, angle C = 60°, angle A = ?
