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
