Sipplementary angles always add up to 180 degrees. Just subtract 126 from 180 to get the missing angle.
They are 41, 42 and 43.

To find out what percent of 126 is 22, you can set up a proportion. Let x represent the unknown percentage. The proportion would be: x/100 = 22/126. Cross-multiply to get 126x = 2200. Divide both sides by 126 to solve for x, which equals approximately 17.46%. So, 22 is approximately 17.46% of 126.
Two angles are supplementary if they add up to 180 degrees. Therefore: 126 + 54 = 180 so the supplement of 54 degrees is 126 degrees.
To find the average of numbers, add them up and then divide by the amount of numbers.132 + 140 + 145 + 128 = 545545 / 4 = 136.25
