The bisectors BI and CI of ∠B and ∠C of a ∆ ABC meet in I. If ∠A = 38°, then what is ∠BIC equal to?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 109°.
According to the given question, ∠BIC = 90° + ∠A/2
⇒ ∠BIC = 90° + 38°/2
⇒ ∠BIC = 90° + 19°
⇒ ∠BIC = 109°
