The Triangle Angle Sum Theorem states that the sum of the angles in a triangle is always 180°.

Given the two angles:

  • First angle = 25°
  • Second angle = 68°

To find the third angle, you can use the following calculation:

\[ \text{Third angle} = 180° - (\text{First angle} + \text{Second angle}) \]

\[ \text{Third angle} = 180° - (25° + 68°) \]

\[ \text{Third angle} = 180° - 93° \]

\[ \text{Third angle} = 87° \]

So, the answer is 87°.
