If A and B are the angles, then
A + B = 180 and A - B = 130 gives 2A = 310 so that A = 155 and then B = 25

Complementary angles add up to one right angle (90 degrees), such as 30 degrees and 60 degrees. Supplementary angles add up to a straight angle, which is 2 right angles (180 degrees). So the supplement of a 30 degree angle is 150 degrees. For any given angle, its supplement is 90 degrees greater than its complement.
Supplementary angles have a sum of 180 degrees.
Supplementary angles have a sum of 180 degrees, while complementary angles have a sum of 90 degrees.
Complementary angles add up to 90 degrees and Supplementary angles add up to 180 degrees. 125+55=180 so these angles and supplementary.
supplementary angles add up to 180 degrees
