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

Given the two angles:

  • Angle 1 = 25°
  • Angle 2 = 68°

First, we add these two angles together:

25° + 68° = 93°

Next, we subtract this sum from 180° to find the third angle:

180° - 93° = 87°

Therefore, the third angle measures 87°.

The correct response is 87°.
