Answer:
1=  70
2= 65
3=  95
For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)

Answer:
6,720 ways
Step-by-step explanation:
Since in the problem arrangemnt is being asked this is a problem of permutation.
No . of ways of arranging r things out of n things is given by 
P(n,r) =   n!/(n-r)!
In the problem given we have to arrange 5 objects from set of 8 objects. 
Here n = 8 and p = 5
it can be done in in 
P(8,5) =   8!/(8-5)! ways
8!/(8-5)!  = 8!/3! = 8*7*6*5*4*3!/3! = 8*7*6*5*4 = 6,720 
Thus,  number of ways to  arrange 5 objects from a set of 8
different objects is P(8,5) =   8!/(8-5)! =  6,720 .
