pre-calc HELP PLEASE

solve using identities for all angles (dont use multiple angle method)show work please cuz i am so confused.

asked by Kimberly
  1. dunno what you mean by "dont use multiple angle method" since

    sin2x = 2 sinx cosx

    4sinx cosx - 3sinx = 0
    sinx(4cosx - 3) = 0

    sinx = 0, so x = 0,180,360,...

    cosx = 3/4, so x = 41.4,318.6,...
