If I be the incentre of ΔABC and ∠B = 70° and ∠C = 50°, then the magnitude of ∠BIC is

If I be the incentre of ΔABC and ∠B = 70° and ∠C = 50°, then the magnitude of ∠BIC is Correct Answer 120°

According to question,
Triangles mcq solution image
As we know that
   ∠A + ∠B + ∠C = 180°
∴ ∠A = 180° -70° - 50°
   ∠A = 60°
∴ ∠BIC = 90° + $$\frac{1}{2}$$ × 60°
   ∠BIC = 120°
