ABC and DEF are right triangles.
Each side of ΞABC is twice the
length of the corresponding side of
ΞDEF.
then
(The area of ΞDEF)/(The area of ΞABC) >1/2 or
ps:explain..
Most probable cases for coin type questions:
1. who picks the last coin and loses the game
2. who picks the last coin and wins the game
case 1 :
If A wants to win the game he should make number of coins in the from = (max+min)k+1 after his chance
case 2 :
If A wants to win the game he'll try to make number of coin in the form = (max+min)k
where k is a natural number
l/m+ n= m/n + l= n/l + m= k , where
k is a real number.
k = or > or
