Answer:
49°, 59°, 72°
Step-by-step explanation:
Angles of a triangle must add up to 180°.
49° + 59° + 72° = 180°
28° + 58° + 62° = 148°
39° + 89° + 108° = 236°
45° + 70° + 85° = 200°
Only the first set could represent the interior angles of a triangle.
The first choice.
The 3 angles must add up to 180 degrees.
49 + 59 + 72 = 108 + 72 = 180.
So it is the first choice.
i am so sorry but i dont know
