Two angles are complemtary if their sum = 90. Two angles are supplemtary if their sum = 180. 55.1 + 124.9 = 180 55.1 + 119.9 = 175 55.1 + 49.9 = 105 Therefoe 55.1 + 124.9 = 180 are supplements.

In a rectangle all angles are right angles, which means they measure 90 degrees.

LCD = 40 14 9/40

The LCD is 20. You will get 7 8/20 - 2 15/20. In the fraction, you can't subtract 15 from 8. Therefore you have to borrow 1 from 7. (20/20 = 1--so add 20 to 8, gives 28). 6 28/20 - 2 15/20 = 4 13/20

The LCD is 36. You will get 11 9/36 - 5 32/36. You cannot subtract the fraction, therefore you have to borrow one from the 11 (36/35 = 1 Then add 9 to 36 which gives 45). 10 45/36 - 5 32/36 = 9/36 = 1/4 You have to reduce the fraction.
