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 : |
|
Answer» `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. |
