Please help
I literally have no idea what to do

1. x=π/6+πn, 5π/6+πn

2. x=2π/3+2πn, 4π/3+2πn, π+2πn

3. x=5π/6+πn, 5π/3+πn

4. 2+√3

5. -(√(2-√3))/2

c. side angle side. u shares the same sides

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
