\cot x \operatorname{coty}=k

and

x+y=\pi / 3

, then

\tan x, \tan y

satisfy the equation

View answer and explanation

Correct option: A

k t^{2}-\sqrt{3}(k-1) t+1=0

Option A is correct because it represents the quadratic equation whose roots are

\tan x

and

\tan y

, derived from the given conditions

\cot x \cot y = k

and

x + y = \pi/3
