Complete your homework and submit it to your instructor.

For problems 1 and 2, determine how many solutions there are for each triangle. You do not have to solve the triangle.

1. A = 29°, a = 13, c = 27 
2. A = 100.1°, a = 20, b = 11 

For problems 3-6, solve each triangle using the Law of Sines. If there is no solution, write “no solution.” Round each answer to the nearest tenth.

3. A = 41°, B =61°, c = 19
4. A = 125.4°, a = 33, b = 41
5. A = 76°, a = 15, b = 5
6. A = 97.5°, a = 13, b = 9
