(iii) Incentre of the triangle ABC is O, If `angle BAC = 40^@`, then `angle BOC = `

(ii) Orthocentre of the triangle ABC is O, If angle BAC=40^@ , then angle BOC=

(i) The circumcentre of the triangle ABC is O, If angle BOC=80^@, then angle BAC=

O is the circumcentre of the triangle ABC. If angle BAC =50^@ , then angleOBC is equal to

The circum-centre of a triangle ABC is O. If angle BAC = 85 ^(@) , angle BCA =75^(@) , then angle OAC is of

(xi) O is the orthocentre of the DeltaABC If angle BAC=55^@ , then angle BOC=

O is the circumcentre of the triangle ABC and angle BAC = 85^@ , angle BCA = 75^@ , then the value of angle OAC is

If I is the incentre of triangle ABC and angle BIC = 135^@ , then triangle ABC is यदि I त्रिभुज triangle ABC का अंतः केंद्र है और angle BIC = 135^@ तो triangle ABC है-

I is the incentre of Delta ABC of angle A = 46^@ , then angle BIC = ?
