Step 1: Identify the given information and definitions. The problem refers to Figure 5.69, which shows two secants AE and AD intersecting at an external point A. We are given: • m( COE) = a, which means the measure of arc CE is a. • m( BOD) = b, which means the measure of arc BD is b. • x = m( BAE) (or m( CAE) as used in the final line). Step 2: Apply the inscribed angle theorem. Chords BE and DC are drawn. • The angle CBE is an inscribed angle that subtends arc $CE
