Find the value of x in the triangle shown below.

Answers

Answer:

x=8

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = 10^2

36 + x^2 = 100

Subtract 36 from each side

36-36 +x^2 = 100-36

x^2 = 64

Take the square root of each side

sqrt(x^2) = sqrt(64)

x = 8

Answer:

x = 8

Step-by-step explanation:

According to Pythagorean Theorem

AB {}^(2) + BC {}^(2) = AC {}^(2)

here

AB = x \n BC = 6 \n AC = 10

Now,

{x}^(2) + {6}^(2) = 10 {}^(2) \n {x}^(2) = {10}^(2) - {6}^(2) \n x {}^(2) = 100 - 36 \n {x}^(2) = 64 \n x = √(64) \n x = 8

AB =x =8

Step-by-step explanation:

Coordinates of point B = (8, -6)

Reflection across the x-axis results in:

  • (x, y) → (x, -y)

Coordinates of B'

  • (8, -6) → (8, -(-6)) = (8, 6)

Let favorable event“1,2,3” represent preferring the toothpaste and sample space “0,4,5,6,7,8,9” represent not recommending the toothpaste. Option B is correct.

Three out of every ten dentists recommend a certain brand of fluoride toothpaste. Which assignment of random digits would be used to simulate the random sampling of dentists who prefer this fluoride toothpaste to determine.


What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.


While going throughout the option in options C and D number so the sample is not equal to 10 so both the statement is false. Option B is the correct option because the sample space is also equal to 10 and the number of the favorable events is also 3 which is mentioned in the question.

Thus, let favorable event “1,2,3” represent preferring the toothpaste and sample space “0,4,5,6,7,8,9” represent not recommending the toothpaste. Option B is correct.
