[" If the biserlow of angles "/_ABC" and "/_A(B" of "0" triangle "],[" ABC met at a point "0," then "/_BOC=10^(@)+(1)/(2)LA]

The bisectors of the angles ABC and BCA of a triangle ABC meet in a point 0. What is the angle at O facing the side BC ?

The sides AB and AC of ABC are product to P and Q respectively.the bisectors of exterior angles at B and C of ABC meet at O( fig..19) prove that /_BOC=90^(@)-(1)/(2)/_A

In ABC, if /_B=60^(@),/_C=80^(@) and the bisectors of angles /_ABC and /_ACB meet at a point O, then find the measure of /_BOC .

O is the incentre of Delta ABC and angle A=30^(@) , then find angle BOC .

In a triangle ABC, if 2 /_A = 3 /_ B = 6 /_ C, then /_B = ?
