Answer: 283 degrees (i think)
Step-by-step explanation:
180
2 * 90
2 * 3 * 30
2 * 3 * 2 * 15
2 * 3 * 2 * 3 * 5
2^2 * 3^2 * 5 <===
Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
