Asalamualaikum tolong di bantu ka,sama caranya:) tentukan nilai sin270°.cos135°.tan135° ___________________ sin150°.cos225° (tunjukan cara menemukan nilai tiap

sin 270 = -1
cos 135 = cos (180-45) = -cos 45 = -½√2
tan 135 = tan (180-45) = -tan 45 = -1
sin 150 = sin (180-30) = sin 30 = ½
cos 225 = cos (180+45) = -cos 45 = -½√2

(-1)(-½√2)(-1) / (½)(-½√2)
= 1 / ½
= 2
