Since O is inscribed in triangle ABC, you know that AB, AC, and BC are all tangent to the circle. The tangent segments theorem asserts that AD is congruent to A F; BD is congruent to BE; and CF is congruent to CE. (NOTE: E is the point where the circle touches BC - I've taken the liberty of labeling it as such.)
Then the perimeter 
of triangle ABC will be twice the sum of the labeled edges:
It’s a obtuse angle which over 90 degrees
