Explanation:
if you are unresponsive then the doctor's goal is to find out why and get you safely back to a responsive state.
and if your life is in danger then emergency operations will take place and if your dont have a band on your arm (like a DNR (do not resuscitate)) then they can take measures that are necessary to save your life (they make armbands for if your religious and dont want doner blood or if your heart stops then you dont want to be brought back my unnatural means like CPR. and doctors by law have to follow that.
Note.... sin (-θ) = -sin(θ)
And tanθ =√15 / 15 = 1 / √15
So
-sin (θ) = -1/4 ⇒ sin (θ) = 1/4
And
tan (θ) = sin (θ) / cos(θ) rearrange as
cos (θ) = sin (θ) / tan (θ) = (1/4) / (1/ √15) = (1/4) * (√15 / 1) = √15 / 4 ⇒ C
