Since you know that tan @ = P/B that is AB/AC. And the opposite of tan @ is cot@= B/P that is AC/AB.
I hope it will help you to understand.

Consider the height of the tree is 'x' m. Then the shadow is (3)^1/2. And apply tan or cot based on the relation which you want to find.

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