To list the angles in order from least to greatest we have to analise the relation of the sides so:
1) the shortest side will be te one between the two longest sides so in this case is the angle between the sides 40 and 38
2)the next one will be the angle between the longest side and the shortest side so in this case is the angle between 40 and 36
3) and finally is the angle between the two shortest sides so is the angle between 38 and 36
