A. 1
B. √3/3
C. √3/2
D. 1/2​

Answer 1

Answer:

Hey frnd...

Here is ur ans...

Step-by-step explanation:

$2 \cos(theta) = \sqrt{3} \\ \cos(theta) = \frac{ \sqrt{3} }{2} \\ \cos(theta) = \cos(30) \\ thus \: theta = 30 \\ now \\ = \cos(theta) \times \tan(theta) \\ = \cos(30) \times \tan(30) \\ = \frac{ \sqrt{3} }{2} \times \frac{1}{ \sqrt{3} } \\ = \frac{1}{2}$

Hope this helps u...
