The easiest way to find the value of sin(20) is to use a scientific calculator or a computer.
But if you want to actually calculate it, you could try the following. First you need to make sure that the angle is expressed in radians. 180 degrees = pi radians so 20 degrees =20*pi/180 = pi/9 radians. Call this value x.
Then find x/1! - x3/3! + x5/5! - x7/7! + ...
The further you go, the more accurate your result.

How do you calculate win- lose?
To calculate win-lose, add the wins and the losses and divide the sum into the wins to calculate percentage of wins or divide into the losses to calculate the percentage of losses: W + L = Total; W ÷ Total = W%; L ÷ Total = L%: example: 12 W + 8 L = 20; 12W ÷ 20 = .60 or 60% wins; 8L ÷ 20 = .40 or 40% losses
