How can say that cot 30°? tan 60 is not compatitable at all I think sin60 or cos60 would be right choice.

Cot θ = root 3.
Then θ =30°; I can't understand this step, can anyone this calculation?

Hey answer is cot 30 degrees but we can also say tan 60 degrees.
Because in the options 60 also there.

@Aditya.
We can choose any ratio either tan or cot.
But, which relates both adjacent and height.

Cot θ= AC/AB.
Cot θ =(3 * AB)/AB,
Cot θ= 3.
Therefore :
θ = 30.
Cot θ =(3 * AB)/AB,
Cot θ= 3.
Therefore :
θ = 30.

@Lavanaya.
How you cancel "x/root 3x" as "x/root3"? I think it is wrong.

This can be tan 60 also right, because the value of tan 60 is √3.
