Solution
40°, 132°, 18°
Explanation:
We know that, the sum of the interior angles of a triangle is 180°.
Now, we will verify the given triplets:
- 67° + 51° + 62° = 180°
- 70° + 83° + 27° = 180°
- 90° + 70° + 20° = 180°
- 40° + 132° + 18° = 190°
Clearly, triplets in 40°, 132°, 18° cannot be the angles of a triangle.
