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°
Fn= (5x+3)+(7x-9)
i have made it simpler
solve it
and u will get the answer

Answer:
40 degrees
Explanation:
A supplementary angle is when two angles add up to equal 180 degrees. So to figure out that one it would be 180-140=40. The other angle is 40 degrees.
