The angles of a triangle always need to add up to 180 degrees.



190 is greater than 180, not equal, so these angles will not form a triangle.
A scientific theory is something believed to be true, thus already tested. When you make an observation you infer, and test your observations to see if they’re true. Please mark me brainliest if I helped :)
