Give the three points on a circle, find the center and radius of the circle: (5,3),(-2,2),(-1,5)

In a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Which type of graph would allow us to compare the median number of teeth for mammals and reptiles easily
