Arnold had three pieces of different color string all the same length. Arnold cut the blue string into 2 equal lengths. He cut the red string into 7 equal-size lengths and the green string into 14 equal-sized lengths. He needs to cut the string so each color has the same number of equal-size lengths.

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?
