In ΔABC, the internal bisectors of ∠ABC and ∠ACB met at I and ∠BAC = 50°. The measure of ∠BIC is

In ΔABC, the internal bisectors of ∠ABC and ∠ACB met at I and ∠BAC = 50°. The measure of ∠BIC is

1. 105°
2. 115°
3. 125°
4. 130°

Answer: Option B
I is the In-centre
So, ∠BIC = 90° + 1/2 ∠BAC
= 90° + 1/2 × 50 = 115°
