Solve the right triangle.

• m<B = 39^o, AB = 11.58, AC = 7.29

• m<B = 39^o, AB = 7.29, AC = 11.58

• m<B = 129^o, AB = 11.58, AC = 7.29

• m<B = 129^o, AB = 7.29, AC = 11.58

Solve the right triangle.

• m<A = 34^o, m<C = 56^o, AC = 5.59

• m<A = 56^o, m<C = 34^o, AC = 5.59

• m<A = 34^o, m<C = 56^o, AC = 9.01

• m<A = 56^o, m<C = 34^o, AC = 9.01
