It is given that the 3 integers add up to 9.
So, we have the sum equation as:

Solving for 
Combining like terms.

Subtracting both sides by 3.


Dividing both sides by 3.


∴ 1st integer = 
2nd integer = 
3rd integer = 
I believe it would be 71 degrees because the total degrees of a triangle is 180 so 57+52=109 then 180-109=71 which would then be the final angle degree.
