Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
complement: 90-67 = 23 degrees supplement = 180-67 = 113 degrees
The supplement of A is 180 - A The complement of A is 90 - A So, 180 - A = 2*(90 - A) + 20 or 180 - A = 180 - 2A + 20 So A = 20 degrees
Suppose the angle is x degrees. Its complement is 90-x So x is 2/3 of (90-x) 3x = 2*(90-x) = 180 - 2x 5x = 180 so that x = 36 degrees
Supplementary angles add up to 180 degrees Complementary angles add up to 90 degrees So: 180-60 = 120 degrees
