Sin 45 = x/12
x=12 x sin 45
x=12 x .7071
x=8.48
There are 21 people, everyone hugs each other, but the person hugging cant hug themself, so (21*21)-21
(21*21) -21 = 441
441-21=420
Okay, its like 1,2,3,4
you want to look at the first number
the one right next to the decimal.
0.099, 0.174, 0.28, 0.679
