Answer 1

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

So, to find the third angle, we can subtract the sum of the other two angles (25° + 68°) from 180 degrees.

180° - (25° + 68°) = 180° - 93° = 87°

Therefore, the third angle of the triangle measures 87°.
