I’m missing information (or a diagram) about where A, B, C, E appear around the circle. As written there are two arcs from B to C (the minor arc BC and the major arc BC), and knowing only arc AB = 76° does not determine either one.
What I can say:
- Arc AB = 76° ⇒ ∠ACB = 1/2·76° = 38°.
- The minor arc BC = 2·∠A, and the major arc BC = 360° − 2·∠A. Neither is determined by the given 76° alone (you would need the measure of another arc or one of the triangle’s angles).
Can you confirm the order of the points around the circle or add any missing information (for example which arc BC E lies on, or another arc or angle measure)? Then I’ll compute arc BEC.
