For number 5, if you know that one angle is 65 degrees, then you can find the angle of the supplementary angle by subtracting it from 180:
180 - 65 = 115 degrees < this is what your supplementary angle will be.
Starting from the top, the graph should read:
115 , 65
65 , 115
115 , 65
65 , 115
For number 6, all of the angles are right angles. We know that all right angles have a degree of 90, therefore every angle should be written as 90 degrees. Additionally, in order to find any supplementary angle, you take the known (90) and subtract it from 180. >> 180 - 90 = 90.
