\tan ^{-1} \mathrm{n}, \tan ^{-1}(\mathrm{n}+1)

and

\tan ^{-1}(n+2), \mathrm{n} \in \mathbb{N}

, are angles of a triangle, then find

\mathrm{n}

View answer and explanation

Correct option: A

Option A (1) is correct because when n=1, the angles are tan^-1(1), tan^-1(2), and tan^-1(3), which can be angles of a triangle.
