If the angle is an inscribed angle then it’s intercepted arc will be double the angles measurements. Therefore if the inscribed angle BAC is 88 degrees then it’s intercepted arc BC will be 176 degrees.
They can make 4 teams and have 4 players that won’t be in a team.
This is because 5*5 is 25 but they don’t have 25 players so you would have to go down which is 4*5=20. Sorry if that’s very confusing but hope that helps!
