Answer 1

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

To find the third angle, you can subtract the sum of the two given angles from 180 degrees:

1. Add the two given angles: \( 25° + 68° = 93° \)

2. Subtract this sum from 180°: \( 180° - 93° = 87° \)

So, the measure of the third angle is 87°.

The correct response is: 87°.
