Find the values of theta lying between 0 degrees and 360 degrees when cos theta = sin 285 degrees? Share with your friends Share 3 Anuradha Sharma answered this cosθ=sin285=sin270+15=-cos15=cos165So the general solution can be given as, θ=2nπ±165Now putting n = 0,1,2,3,4.. we get, θ=165, 195 degree 6 View Full Answer
