all angles of a triangles add to 180 degrees.180 - 110 - 35 = 35 is your answer
The 3rd angle is: 180-55-80 = 45 degrees
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
If that is the angles of a triangle then the 3rd angle is 110 degrees
The 3 angles of a triangle always add up to 180 degrees. You have 110 and 43, so that is 153 degrees. Subtract 153 from 180, and that is the remaining angle.
