s=8*[95*pi/180] s=8*19/36pi
LynFran
  • LynFran
we had to convert the degree to radians first

Ok
LynFran
  • LynFran
so s=(38/9)pi and since pi=3.14 we get (38/9)*3.14

so???
LynFran
  • LynFran
so s=13.257 when rounded =13.26

|dw:1435985427041:dw| it would be a 315 degree angle so...cos theata=\[(\frac{ \sqrt{2} }{ 2})\], sin theta=\[(\frac{ -\sqrt{2} }{ 2 })\]and tan theta= -1
