the average of the least two angles will be 117 degrees and angles will be 114 and 120 degrees.

All angles will be
114,120,126,132,138,144,150,156.
smallest angle = 114
diff in angles = 6 deg
avg of largest and second largest angle = (150+156)/2= 153 deg
average of the least two = (114+120)/2 =117 deg
