In a `Delta ABC` the value of `/_A` is given by 5 CosA - 3 = 0 then the equation whose roots are sinA and tanA is :

Explanation

`5cosA-3=0`

`cosA=3/5, sinA=sqrt(1-cos^2A)=4/5`

`tanA=4/3`

Sum of roots=`4/3+4/5=32/15`

Product of roots=`4/3*4/5=16/15`

`x^2-(32/15)x+16/15=0`

`15x^2-32x+16=0`

option d is correct.
