To find the sum of the angles of a triangle, we need to add the measures of the three angles together.
Given that two of the angles measure 25° and 68°, we can add them together:
25° + 68° = 93°
The sum of the three angles of a triangle is always 180°.
To find the measure of the third angle, we can subtract the sum of the other two angles from 180°:
180° - (25° + 68°) = 87°
Therefore, the third angle of the triangle measures 87°.
