Note that C-B is considered the hypotenuse of the of traingle. Therefore, according to the acronym SOH CAH TOA, Cos C = Adjacent/ Hypotenuse, where the adjacent is 8√34 and the hypotenuse is given by by pythagoreas theorem (a²+b² = c²) or c=√(a²+b²) → c=√4352
Then Cos C = (8√34) /(√4352) → this simplifies into √2 on the top and 2 on the bottom once we simplify.
Final Answer: 
Answer:
Step-by-step explanation:
31.62
Because 31.62 times itself is a 1000
Answer:
The answer is k=77
Step-by-step explanation:
It is given that n is an integer and greater than 2. Let us simplify k = (n + 2)(n – 2) to k=n^2-4.
In (1) it is stated that k is the product of two primes and in (2) it is stated that k<100. To solve the question we need to consider both cases (1) and (2).
Let say n=9 then k=n^2-4 becomes k=81-4=77. Well, 77 is the product of two prime numbers 7 and 11 (77=7*11). The answer is k=77
I believe 30, because there are six ways in and five ways out, five because you can't go back through the same entrance. So six times five is thirty.
Answer:
C. 20
Step-by-step explanation:
45 + 5x + 35 = 180
5x + 80 = 180
subtract 80 from both sides
5x = 100
divide by 5
x = 20
