					 O is the in-centre of the ∆ABC, if ∠BOC = 116°, then ∠BAC is
- 
                        -  42°
 
-  62°
 
-  58°
 
- 52°
 
-  42°
Correct Option: D
On the basis of given in question , we draw a figure triangle ABC in which O is the in-centre ,
The point of intersection of internal bisectors of a triangle is called in-centre.
| ∠BOC = 90° + | 2 | 
| ⇒ 116° = 90° + | 2 | 
| ⇒ | = 116° - 90° = 26° | 2 | 
∴ ∠A = 26 × 2 = 52°
