In binary tree there are
n ancestor at level n.
Proof :
Take P(0): At node level
0, it has no ancestors since this is a roo tnode.
Take P(1): At node level
1, it has one ancestor. The ancestor is the root, its parents which is at level
0.
Take P(K): A node level
K it has K ancestors. Its parent is at level K – 1.
Take P(K+1): At node K +
1 level have more than one ancestor than that of node at k level.
<span>Thus there are n ancestor
at level n in binary tree.</span>
23% of 115....turn percent to decimal by dividing by 100..."of " means multiply
0.23(115) = 26.45....so Joanne spent 26.45 on the shirt.
Any natural or whole number works I believe. 1,2,3,4,5,6,7,8,9,10,11etc. Hope this helps
The angle does not matter. Think of it as finding the other side to a triangle. Use
a=39 (line AB)
b=b (the leg we need to find)
c=89 (line BD)
(subtract the 1521 from both sides)
(square root both sides)
b = 80
AD=80
