That’s a tricky stem and leaf plot, Anw as the key shows 11|6 =16
So the most common arm span is 12 the least commons are 11,17,19,22 which appear only one time. So I’d say there are no outliers
(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
