Three angles are given; Start with angle measures 80,40, and 60. try other sets of angles such as 20, 120, and 40. try three measures that dont add up to 180

Answer: 30, 60 and 80

Step-by-step explanation:

measures 80,40, and 60. And sets of angles such as 20, 120, and 40 will make two different triangles.

To try three measures that dont add up to 180 will never make a triangle.

One of them can be 30, 60, 80
