Solve the right triangle.

• <B = 39^o, AB = 11.58, AC = 7.29

• <B = 39^o, AB = 7.29, AC = 11.58

• <B = 129^o, AB = 11.58, AC = 7.29

• <B = 129^o, AB = 7.29, AC = 11.58

Solve the right triangle.

• <A = 33.7^o, <C = 56.3^o, AC = 5.59

• <A = 56.3^o, <C = 33.7^o, AC = 5.59

• <A = 33.7^o, <C = 56.3^o, AC = 9.01

• <A = 56.3^o, <C = 33.7^o, AC = 9.01
