In Figure, `A ,B , C` are three points on a circle such that the angles sub center `O` are `80^@ and 120^@` respectively. Determine `/_B A C` and the degree measure of arc `BPC`

In Figure,A,B and C are three points on a circle such that the angles subtended by the chords AB and AC at the centere O are 90^(@) and 110^(0), respectively.Determine /_BAC .

A, B and C are three points on a circle such that the angles subtended by the chords AB and AC at the centre O are 110°^(@) and 130^(@) respectively. Then the value of angleBAC is :

A, B and C are the three points on a circle such that the angle subtendsed by the chords AB and AC at the centre O are 90^@ and 110^(@) respectively. angle BAC is equal to

A, B and C are three points on a circle such that the angles subtended by the chords AB and AC at the centre O are 80^@ and 120^@ , respectively. The value of angle BAC is: A, B तथा C एक वृत्त पर स्थित तीन ऐसे बिंदु हैं कि जीवाओं AB तथा AC के द्वारा केंद्र पर अंतरित कोण क्रमशः 80^@ तथा 120^@ हैं | कोण BAC का मान क्या है ?
