Given

we are given an angle of 285 degrees.

Required

we need find sin, cos and tan of 285 degrees

Step-by-step explanation

Here we know that


sin(360-x)=-sinx

so


\begin{gathered} sin(285)=sin(360-75)=-sin(75) \\ =-(√(6)+√(2))/(2)=-0.97 \end{gathered}

Again


cos(360-x)=cosx

so


\begin{gathered} cos(285)=cos(360-75)=cos(75) \\ =0.25 \end{gathered}

and finally


tan(360-x)=-tanx

so


\begin{gathered} tan(285)=tan(360-75)=-tan75 \\ =3.73 \end{gathered}
