In the given diagram, the points a, b, and c lie on a circle whose center is o. boc is a diameter of the circle. the following set of premises is relevant to the investigation of the given geometric diagram: i. the radii of a circle are of equal length. ii. angles opposite to equal sides of a triangle are equal. iii. the sum of the angles of a triangle is 180°. with reference to the diagram, which conclusion can be drawn correctly from the premises? a) ac = co b) oa + ob + ab > ∠bac c) m∠aco < 45° d) m∠bac = 90°

Applying premise i,  oa = ob and oa = oc.applying premise ii, to  δoab, m∠oab = m∠abo = m∠abc.applying premise iii, to  δoac, m∠oac =  ∠aco = m∠acb.now on application of premise iii, it follows that: 2 m∠abc + 2 m∠acb = 180° ⇒ m∠abc + m∠acb = 90°
