costheta/1-sintheta + costheta/ 1+ sintheta =4 is true for the acute angle theta About the author Quinn
Step-by-step explanation: Answer cosθ+sinθ cosθ−sinθ = 1+ 3 1− 3 cosθ cosθ+sinθ cosθ cosθ−sinθ = 1+ 3 1− 3 1+tanθ 1−tanθ = 1+ 3 1− 3 On comparing the two sides, we get, tanθ= 3 =tan60 o θ=60 o Reply
