| The central angle inscribed in the circle of the triangle is equal to the arc on which it rests => angle AOB = arc AB The inscribed angle is equal to half of the arc on which it rests => ACB = 1/2 of arc AB Based on this, we can conclude that the inscribed angle equal to half of the central angle resting on the same arc ACB = 1 / 2AOB = 36.5.
