To find the measure of angle C, we need to use the Triangle Angle Sum Theorem. The sum of the three angles in a triangle must equal 180°.
Given that angle B measures 155° and angle A measures 25°, we can find the measure of angle C by subtracting the sum of angles A and B from 180°:
C = 180° - (25° + 155°)
C = 180° - 180°
C = 0°
Therefore, the measure of angle C is 0°.
