Cos30 = sin(90 - 60) = √3/2, because cos and sin are complements
cos120 = cos(180 - 60) = -cos60 = -1/2
I would probably say (0,0) just because (5,0) falls on the x-axis and not on the y-axis and the other are just regular plotting coordinates. (0,0) is the only one that falls on the y-axis although it still falls on the x-axis as well
-29
-5(6) + 1
-30 + 1
-29
hope this helps !
