1/5 is 2% or 0.2, therefor 2/5 is 4% or 0.4
Since it’s a 10 team league and each team plays with the other team twice then 10+10=20, thus there would be 20 games played
Ok what is it that u need
Two supplemental angles add up to 180°
So we have (A + B = 180°)
The measure of one of them is always 180° - the other.
A = 180° - B
B = 180° - A
