sin space 30 degree times cos space 60 degree plus cos space 30 degree times sin space 60 degree equals 1

Pembahasan

Jadi,

$table attributes columnalign right center left columnspacing 0px end attributes row cell sin space 30 degree times cos space 60 degree plus cos space 30 degree times sin space 60 degree end cell equals cell 1 half times 1 half plus fraction numerator square root of 3 over denominator 2 end fraction times fraction numerator square root of 3 over denominator 2 end fraction end cell row blank equals cell 1 fourth plus 3 over 4 end cell row blank equals cell 4 over 4 end cell row blank equals 1 end table$

Jadi, sin space 30 degree times cos space 60 degree plus cos space 30 degree times sin space 60 degree equals 1
