Answer 1

I’m not able to read the diagram/notation from the text you pasted. I need one clarification before I can solve this correctly:

- Are A, B, C, D points on a circle (a cyclic quadrilateral) or not?
- Which quantities are arcs and which are angles? For example, does "mBC = 58°" mean the measure of arc BC = 58°, or does it mean m∠BC? And what does "m = 106°" refer to (m∠C? m(arc CD)? m∠something else?)
- If possible, please retype the givens as plain text (for example: m∠B = 93°, arc BC = 58°, arc CD = 106°) or attach a picture of the diagram.

While you clarify, here are the rules I’ll use depending on the situation so you know what I’ll do once I have the correct interpretation:

- If the points are on a circle, an inscribed angle = 1/2 the measure of its intercepted arc.
- In a cyclic quadrilateral, opposite angles sum to 180° (m∠A + m∠C = 180°, m∠B + m∠D = 180°).
- A central angle equals the measure of its intercepted arc.

Send the clarified givens (or a photo) and I’ll compute m∠A, m∠C, and m∠D.
