    mBC is not a valid way of describing an angle on a diagram

    its a bit of trick question. I've just worked out that mBC is the measure of the angle subtended by arc BC. So it's really just a triangle problem

    If you draw two lines between the centre of the circle, O with B & C then you get a triangle with angle BOC = 76 deg

    Problem is you have no idea why it's 38 deg
