Question

in rectangle abc incenter is o and boc is 110 measure bac

Answer 1

@rawat Please post a diagram so that we will know where to find angle BOC.

Also, I think "in rectangle abc incenter" should be "triangle ABC" because triangles have incenters. The incenter is the point of concurrency (intersection) of the three angle bisectors of the triangle and is the center of the circle that can be inscribed within the triangle.
