Ranking is very critical in this problem. Therefore, the most applicable mathematical theory is permutations.
Ranking possible for the cellists:
Needed cellists = 5
Total available cellists = 10
Possible number of rankings = 10P5 = 10!/(10-5)! = 30240
Ranking possible for the violinists:
Needed violinists = 5
Total available = 16
Possible number of rankings = 16P5 = 16!/(16-5)! = 524160
Therefore,
Ratio of rankings (cellists to violinists) = 30240/524160 = 3/52

Answer:
right angel triangle means one of the three angel is 90
also it is given that two sides are equal
there for it is an isoselas triangle means other two triangles are equal
let the other two angels be x then
then 90 + x + x = 180
2x = 180 - 90
x = 90 ÷2
× = 45
prof. 90 + 45 + 45 = 180
