Answer:

we know, tan = perpendicular/ base so, after comparing , perpendicular = 3 and base = 4 ∴ hypotenuse = √(3² + 4²) = 5 now, sin ...

Step-by-step explanation:

4tan \alpha  = 3  \\ tan \alpha  =  \frac{3}{4}

 \frac{4 \sin( \alpha )  -  \cos( \alpha )  }{4 \sin( \alpha  +  \cos( \alpha ) ) }  =  \frac{4 \ \frac{ \sin( \alpha ) }{ \cos( \alpha )  }  -  1 }{4 \frac{ \sin( \alpha ) }{ \cos( \alpha ) } + 1 }  =  \frac{4 \tan( \alpha )  - 1 }{4 \tan( \alpha ) + 1 }

 \frac{4( \frac{3}{4} )  - 1}{4( \frac{3}{4} + 1 }  =  \frac{3 - 1}{3 + 1}  =  \frac{2}{4}   =  \frac{1}{2}
