The Triangle Angle Sum Theorem states that the sum of the angles in a triangle is always 180 degrees.
Given the two angles:
- Angle 1: 25°
- Angle 2: 68°
To find the third angle (let's call it Angle 3), we can use the following formula:
\[ \text{Angle 3} = 180° - (\text{Angle 1} + \text{Angle 2}) \]
Substituting the values:
\[ \text{Angle 3} = 180° - (25° + 68°) \]
Calculating the sum of the first two angles:
\[ 25° + 68° = 93° \]
Now subtract this sum from 180°:
\[ \text{Angle 3} = 180° - 93° = 87° \]
Therefore, the measure of the third angle is 87°.
