The sum of the interior angles of a triangle is 180. Add the three measures given and if you get 180 then those can be the interior angles of a triangle.
We use BEDMAS and we go from left to right
Therefore; 1. 9+34 = 43
2. 43+5452 = 5495
3. 5495 -49349 = -43854
4. -43854+4 = -43850
Final Answer is - 43' 850.
