Answer 1

To find the third angle of a triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180°.

Given that two angles measure 25° and 68°, we can find the third angle by subtracting the sum of these two angles from 180°.

Third angle = 180° - (25° + 68°)
Third angle = 180° - 93°
Third angle = 87°

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