Step-by-step explanation:

tan theta = 1/tan 2theta

tan theta = cot 2theta

tan theta = tan(90-2theta)

theta = 90-2theta

3theta = 90

theta = 30

Answer:

9/4

Step-by-step explanation:

use fromula of tan2x= 2tanx/1-tan^2 x

then we will get from given equation tanx=1/√3

so we get theta = 30°

then by putting π/6 in required equation then the ans will be 9/4
