Answer:
D.130°
Step-by-step explanation:
An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.
-Given that AC and BC are diameters, then since they are alternate angles.
#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:
Hence, mBC=130°
