What is the measure of AC?
А. 299
В. 122
с. 58
D. 116°

Answer:
○ D. 116°
Step-by-step explanation:
Think of the Unit Circle. You know that half of 360° is 180°, and that angle has a measure of 58°, so you do this:
-58° + 180° = 122°
Now, that chord of the circle drags it a bit by a few units, so that will be approximately 116°.
