Answer:
There are 945 ways to make the pairings
Step-by-step explanation:
Lets pick a team. There are a total of 9 ways to select its pair. Now we have 8 teams remaining, note that the team we picked at the start doesnt matter because it will eventually be picked and the order doesnt matter. From the 8 teams remaining we select one of them and we pick a pair for it; we have 7 possibilities since we hace 7 teams remaining.
From the 6 teams remaining we take one of them and we select its partner, we now have 5 possibilities. From the 4 teams remaining we select one of them and pick 1 of the 3 teams remaining as its pair. Then, we pair the remaining teams.
This gives us a total of 9*7*5*3 = 945 ways to pair the teams.

Answer: m=45° n=15°
Step-by-step explanation:
ok so idk if you know about the 45-45-90
the first triangle has a 45° angle and 90° angle.
these equal to 135°, 180- 135 is 45.
so m= 45°.
the other triangle looks like it could be equilateral.
so that's 60-60-60.
since m= 45°
60-45= 15
therefore n= 15°
