2 tan 30°
$\div$

1 -tan 30°
(A)
cos 60°
(B) sin 60
(C) tan 60°
(D) sin 30°
please ans this question in full basic manner please.................​

Answer 1

Answer:

$\frac{2 \tan( {30}^{0} ) }{1 - \tan( {30}^{0} ) } = \frac{ \frac{2}{ \sqrt{3} } }{1 - \frac{1}{ \sqrt{3} } } = \frac{2}{ \sqrt{3} - 1}$

None of these

Answer 2

Answer:

because, tan2A=2tanA/1-tan^2A

therefore, 2tan30°/1-tan^2 30°=tan 2×30°=tan60°.

this is your answer.

please mark as brainliest.
