Pembahasan Soal:

Dengan menggunakan rumus trigonometri sudut berelasi pada kuadran II, maka:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell sin left parenthesis 180 minus a right parenthesis degree end cell equals cell sin space a degree end cell row cell cos left parenthesis 180 minus a right parenthesis degree end cell equals cell negative cos space a degree end cell row cell cosec left parenthesis 180 minus a right parenthesis degree end cell equals cell negative sec space a degree end cell row cell cot left parenthesis 180 minus a right parenthesis degree end cell equals cell negative cotan space a degree end cell row cell sec left parenthesis 180 minus a right parenthesis degree end cell equals cell sec space a degree end cell row blank blank blank row cell straight a. space sin space 136 degree end cell equals cell sin left parenthesis 180 minus 44 right parenthesis degree end cell row blank equals cell sin space 44 degree end cell row blank blank blank row cell straight b. space cos space 105 degree end cell equals cell cos left parenthesis 180 minus 75 right parenthesis degree end cell row blank equals cell negative cos space 75 degree end cell row blank blank blank row cell straight c. space cot space 156 degree end cell equals cell cot left parenthesis 180 minus 24 right parenthesis degree end cell row blank equals cell negative cot space 24 degree end cell row blank blank blank row cell straight d. space sec space 140 degree end cell equals cell sec left parenthesis 180 minus 40 right parenthesis degree end cell row blank equals cell negative sec space 40 degree end cell row blank blank blank row cell straight e. space cosec space 116 degree end cell equals cell cosec left parenthesis 180 minus 64 right parenthesis degree end cell row blank equals cell negative cosec space 64 degree end cell end table end style

Jadi, begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight a end table table attributes columnalign right center left
