Answer:
23 degrees
Step-by-step explanation:
If <ADC is the arc measure of the circle, by definition the center angle (<ABC) has the same measure as its intercepted arc.
The common denominator is 40.
Well, 25 certainly doesn't divide evenly into 595, but it does divide into 600, which is <em>very</em> close to 595. So if we divide 600 by 25, we can get a rough estimate of what 595 divided by 25 is.
