Complementary angles add up to a right angle (90°). So 90° - 25° = 65° The way I remember the difference between complementary and supplementary is: think of a Straight line is 180° (Supplementary). Think of a Cross makes a 90° angle (Complementary)
The complementary angle of 51o is 39o; the supplementary angle of 51o is 129o.
To find the complementary angle, you subtract 90 by the first given complement angle. To find the supplementary angle, you subtract 180 by the first given supplement angle.
