The answer is option D. (15°)

Two angles are said to be supplementary when both angles together make a straight line. Since the measure of a straight line is 180°, it then follows that the sum of two supplementary angle is 180°

Let the unknown angle = x
x is supplementary to 165°
⇒ x + 165° = 180°
x = 180° - 165°
x = 15°
