check answer again? @jim_thompson5910
incorrect
you first need to find a coterminal angle to that given one such that it is between 0 and 360
so subtract off multiples of 360
I did this: 1046/360 = 2.905..... Then I took that decimal^, minused 2, then without rounding and multiplied it by 360 and got 326 then i subtracted 180, to get 146, then subtracted 90 to get 56...weird train of thought eh?
326 is the correct coterminal angle for 1046
so...subtracting 360... 1046 - 360 = 686
oh...326. How do i get that into a reference angle?
326 is between 270 and 360, we're in quadrant IV |dw:1416371191011:dw|
draw a perpendicular to the x axis and form this triangle |dw:1416371224944:dw|
the reference angle is here |dw:1416371247673:dw|
this angle is 326 |dw:1416371275886:dw|
