Final answer:
The third angle in the scalene triangle measures 95°.
Step-by-step explanation:
In a scalene triangle, no two angles are equal. Therefore, the third angle in this triangle can be found by subtracting the sum of the two given angles from 180° (the total number of degrees in a triangle).
So, the third angle = 180° - (28° + 57°) = 180° - 85° = 95°.
Therefore, the third angle in the scalene triangle measures 95°.
