Answer:
1,4
Step-by-step explanation:
2 + 1 is 3. 3 + 4 is 7
3 + 1 is 4. 7 + 4 is 11. so it's 1 up and 4 across
The shape of a bst approaches that of a perfectly balanced binary tree, (log2n) is the time complexity for a balanced binary search tree in case of insertions and search.
In computing, binary bushes are mainly used for looking and sorting as they offer a way to save statistics hierarchically. a few common operations that may be conducted on binary trees encompass insertion, deletion, and traversal.
A binary tree has a special situation that each node could have a most of two youngsters. A binary tree has the benefits of each an ordered array and a linked listing as search is as brief as in a taken care of array and insertion or deletion operation are as fast as in related listing.
In pc science, a binary tree is a tree information shape in which every node has at maximum two youngsters, that are known as the left baby and the proper toddler.

Answer:
see the procedure
Step-by-step explanation:
we know that
m∠1+m∠2=180° -----> supplementary angles (form a linear pair)
we have
m∠1=27° ----> given problem
substitute the measure of m∠1 in the equation above and solve for m∠2
27°+m∠2=180°
Subtract 27° both sides
27°+m∠2-27°=180°-27° ----> by subtraction property of equality
m∠2=153°
The answer would be 25...
Think about it, switch 25 with z
Answer 25 - 3 = 22
Correct
Answer:
see explanation
Step-by-step explanation:
Using the addition identity for sine
sin(x + y) = sinxcosy - cosxsiny
Consider the left side
cos²(45 - A) - sin²(45 - A)
cos²(45 - A) = 1 - sin²(45 - A), thus
1 - sin²(45 - A) - sin²(45 - A)
= 1 - 2sin²(45 - A) ← expand sin(45 - A)
= 1 - 2(sin45cosA - cos45sinA)²
= 1 - 2(cosA - sinA)²
= 1 - 2(cos²A - sinAcosA + sin²A)
= 1 - cos²A + 2sinAcosA - sin²A
= sin²A + 2sinAcosA - sin²A
= 2sinAcosA
= sin2A = right side ⇒ verified
