Menentukan panjang AC dengan Teorema Pythagoras.

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row AC equals cell square root of AB squared plus BC squared end root end cell row blank equals cell square root of 4 squared plus 3 cubed end root end cell row blank equals cell square root of 16 plus 9 end root end cell row blank equals cell square root of 25 end cell row blank equals 5 end table end style 

Perbandingan trigonometri:

begin mathsize 14px style sin space beta equals AB over AC equals 4 over 5 cos space beta equals BC over AC equals 3 over 5 tan space beta equals AB over BC equals 4 over 3 cosec space beta equals fraction numerator 1 over denominator sin space beta end fraction equals 5 over 4 secan space beta equals fraction numerator 1 over denominator cos space beta end fraction equals 5 over 3 cotan space beta equals fraction numerator 1 over denominator tan space beta end fraction equals 3 over 4 end style
