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°.
