Answer:
(a) 76°, 64°, 40° and (c) 56°, 62°, 62° these two triplets can be the angles of a triangle.
Step-by-step explanation:
The sum of angles of a triangle is 180°.
- 76° + 64° + 40° = 180°. So, this is triplets can be the angles of a triangle.
- 30°+ 70°+ 90° = 190°. So this is not triplets.
- 56°+ 62°+ 62°= 180°. So, this is triplets can be the angles of a triangle.
