Shiloh Rollins · Answer 1

In a triangle, the sum of the angles is always 180 degrees. To solve this problem, we need to subtract the given angles from 180. The third angle is 52 degrees.

Brandon French · Answer 2

In a triangle, the three interior angles always add to 180°.

56° + 72° + x° = 180°

128° + x° = 180° |subtract 128° from both sides

x° = 52°
