Let the smallest angle be x = y-36    (1)  
           2nd angle be y                    (2)
          largest angle be z = 111+x    (3)

x + y + z = 180
x + y + (111+x) = 180
2x + y = 69 (eqn4)

combining eqn1& 4,

2x + y=  69
 x  - y = -36 
-------------------
3x = 33
x = 11

Therefore,

smallest angle = 11 degrees
2nd angle = x+36 = 47 degrees
largest angle = 111+11 = 122 degrees
