Answer:
The median is four.
Step-by-step explanation:
First you put the numbers in order from least to greatest and write the number as many times as indicated.
2 2 2 3 4 4 4 4 6 6 7 7 7 8 9
then start from one side then go to the other crossing out numbers. So cross out a two, then nine, then another two, then eight, then the last two, then the first seven and so on. When your done you should be left with one middle number, in this case it's four.
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. ... The difference is their sum.
