If a triangle has two angles of 50 degrees and 60 degrees, what is the third angle?

Explanation:
In a triangle, the three interior angles always add up to 180 degrees. With one angle at 50 degrees and another at 60 degrees, the third angle must make the total 180. So the missing angle is 180 minus (50 plus 60), which is 70 degrees. That 70 degrees is the only value that brings the total to 180, so it’s the correct third angle. If the third angle were any other value, the three angles wouldn’t sum to 180, which isn’t possible for a triangle.
