    Answer:

    We have,

    3sinθ+4cosθ=5              ………. (1)

    On squaring both sides, we get

    (3sinθ+4cosθ)  

    2

    =5  

    2

     

    9sin  

    2

    θ+16cos  

    2

    θ+24sinθcosθ=25

    9(1−cos  

    2

    θ)+16(1−sin  

    2

    θ)+12×2sinθcosθ=25

    9−9cos  

    2

    θ+16−16sin  

    2

    θ+12×2sinθcosθ=25

    25−9cos  

    2

    θ−16sin  

    2

    θ+12×2sinθcosθ=25

    9cos  

    2

    θ+16sin  

    2

    θ−12×2sinθcosθ=0

    (3cosθ−4sinθ)  

    2

    =0

    3cosθ−4sinθ=0

    Hence, the value is 0.
