First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
5.1x10^6 is the greatest because when u multiply it, it is 5 million
It would be .5x-5= because it says 5 less so it would be subtract 5 from half of x.
You can only multiply numbers that are inside the radical symbols
I looked it up on google it is 1252
