Answer:
The required equation is 6x+5y+57=0.
A thumb-wrestling match requires two thumbs, so we can either suppose that we need at least two people

, or allow one to thumb-wrestle one's self. In either case, we'd have

, so let's just say we need a minimum of two players.
If we add one more person to the set of players, then the first two people would need to play 1 additional match each. So

.
If we add one more person, then the first three people would again each have to play 1 more match with the new person. So

.
And so on, so that in general, the number of games needed for everyone to play exactly one match with everyone else is given recursively by
Ok, so the 4pi is indicating toward the arc length. Since the radius of the circle is 18, the circumference of the circle is 36pi. If you find the ratio of the arc length to the circumference, you can find the ratio of the indicated angle to the total number of degrees in a circle.
4pi/36pi = 1/9
(indicated angle)/360 = 1/9
(indicated angle = 40
The answer is the 4th choice, or 40 degrees.
