If 3 tan^ 2 θ – 4√3tan θ + 3 =0 then find the acute angle θ.

If 3 tan 2 θ – 43tan θ + 3 =0 then find the acute angle θ.

Solution
3 tan 2 θ – 43tan θ + 3 =0  [Given]
3 tan2 θ – 33 tanθ  -  3 tanθ  + 3 = 0
3tanθ (tanθ - 3) – 3 (tanθ - 3 ) = 0
(tanθ - 3) (3tanθ - 3) = 0  
tanθ - 3 = 0
OR
3tanθ - 3  = 0
tan θ  = 3
OR
3 tan θ = 3

OR
tanθ
=
3



3





OR
tanθ
=
1



3




But, tan 600 = 3

Also,
tan 300
=
1



3



θ = 600
OR
θ = 300



Ans. the value of θ is either 300 OR 600
