Answer 2

Step-by-step explanation:

1. sin -30°= -1/2
2. sin -30°= -1/2cos -30°= √3/2
3. sin -30°= -1/2cos -30°= √3/2tan -30°= -1/√3
4. sin -30°= -1/2cos -30°= √3/2tan -30°= -1/√3cosec -30°= -2
5. sin -30°= -1/2cos -30°= √3/2tan -30°= -1/√3cosec -30°= -2sec -30= 2/√3
6. sin -30°= -1/2cos -30°= √3/2tan -30°= -1/√3cosec -30°= -2sec -30= 2/√3cot -30= -√3
