Answer:
x ≈ 5.3
Step-by-step explanation:
a²+b²=c²
c is always the hypotenuse in a right angle triangle.
6² + x² = 8²
36 + x² = 64
64 - 36 = 28
x² = 28
x = √28
Use calculator from here.
√28 = 5.29150262213
5.29150262213 ≈ 5.3
Because the number after 2, which is 9, is greater than 5, the nearest tenth is 5.3, not 5.2.

Polynomials consist of both indeterminates and coefficients. The factors of the polynomial x² - 15x + 36 is (x-3)(x-12).
What are polynomials?A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.
Given to us
x² - 15x + 36
To find the factors of the polynomial,
[tex]x^2 - 15x + 36 \\\\[/tex]
We will replace -15 with two numbers such that their sum is -15 while, their product must be 36.
[tex]x^2 - 15x + 36 \\\\ = x^2 -12x-3x +36\\\\[/tex]
now, we will take x as the common term from the first two-term, while 3 as the common term from the next two terms.
[tex]= x^2 -12x-3x +36\\\\= x(x-12) - 3 (x - 12)\\\\= (x-3)(x-12)[/tex]
Hence, the factors of the polynomial x² - 15x + 36 is (x-3)(x-12).

Answers
Answer:
First off, I LOVE helping people even if I'm not a professor teacher, or tutor. However, I always do my best to answer the questions as close to perfection as possible even if it can take an hour. I want people to easier to understand and leaner better when I gave an answer to their question, by doing that, I felt very proud of myself and felt like I accomplished a goal. I'm still very young and just started using Brainly, so I don't really know what a brainlist is (DON'T LAUGH). Even so, if you don't think that I deserve the brainlist, it's fine because once I'm older and have more experience, I could help more and more people with their questions or problems. If you actually gave me a brainlist, I'll be really grateful and I might give you a brainlist if you answered my questions. Anyway, when I received a brainnlist, the first thing that came up in my mind is that my answers are actually useful for once. P.s. if you give a brainlist, Thank u

you install 618 feet of fencing along the perimeter of a rectangular yard. The width of the yard is 152 feet. What is the length of the yard?
Answers
Answer:
The length of the yard is 157 feet
Step-by-step explanation:
P= L+L+W+W or 2L+2W. (P is perimeter, L is length, and W is width.)
Substitute in known values for the variables.
618=2L+2(152)
Multiply.
618=2L+304
Now solve for L by doing inverse operations (subtract).
314=2L
Divide.
L=157
So the yard is 157 feet long.

Angela has 3 pennies. She tells her friend that she has 3/10 of a dollar. Is she correct? Why or why not?
Answers
Answer:
Yes
Step-by-step explanation:
She is correct because 3/10 of 100 (a full dollar) is 0.3 which is 3 in pennies/cents. You could also do 3% of 100 which is 3 (pennies/cents)
Is should be 3/100 (0.03 or $0.03)
I penny can be written as $0.01
3/10 is 0.3 or $0.30(which is 30 cents or three dimes)

Which set of numbers could represent the lengths of the sides of a right triangle?

8, 9, 10
9, 40, 41
Answers
Answer:
D. 9, 40, 41
Step-by-step explanation:
We can use Pythagorean theorem (a²+b²=c²) to answer this question by squaring the smallest 2 lengths then seeing if it equals the square of the 3rd length.
2²+3² = 4+9 = 13 ≠ 4²
12²+15² = 144+225 = 369 ≠ 20²
8²+9² = 64+81 = 145 ≠ 10²
9²+40² = 81+1600 = 1681 = 41²

Answers
Answer:
x approximately = 11.971, y approximately = 0.837
Step-by-step explanation:
the 12 ft is the hypotenuse of the right angle triangle formed
Cos (theta) = adjacent/hypotenuse
so Cos(4) = x/12, solving for x = 11.971
Sin(theta) = opposite/hypotenuse
so Sin(4) = y/12, solving for y = 0.837
