 To find the measure of x and the unknown angles in a polygon, we can create an equation based on the sum of the interior angles, which is 540 degrees.final answer is 108°.

Let's assume the polygon has n sides. Each interior angle of a polygon can be calculated using the formula (n - 2) * 180° / n. In this case, we are given that the sum of the interior angles is 540 degrees.
So, we can set up the equation:
(n - 2) * 180° / n * n = 540°
Simplifying the equation:
(n - 2) * 180° = 540°
(n - 2) = 540° / 180°
(n - 2) = 3
Solving for n:
n = 3 + 2
n = 5
Now that we know the polygon has 5 sides, we can find the measure of x by substituting it back into the formula:
x = (5 - 2) * 180° / 5
x = 3 * 180° / 5
x = 540° / 5
x = 108°
In conclusion, the measure of x is 108 degrees, and each of the unknown angles in the polygon would also be 108 degrees since all angles in a regular polygon are equal.

The circumference of the circle is approximately 31.42 cm and the area of the circle is approximately 157.08 cm².

A circle circumscribed about a square with sides of 10cm has a circumference of approximately 31.42 cm and an area of approximately 157.08 cm².

If a circle is circumscribed about a square, the diameter of the circle is equal to the diagonal of the square. In this case, the diagonal of the square is:

d = √(10² + 10²) = √(200) = 10√(2) cm

The radius of the circle is half the diameter, so:

r = 5√(2) cm

The circumference of the circle is:

C = 2πr = 10π√(2) cm

The area of the circle is:

What brings about TB infection?

The bacteria Mycobacterium tuberculosis is the one that causes tuberculosis (TB).

                           When someone who has active TB disease in their lungs coughs or sneezes and the TB bacteria-containing droplets are ejected, the disease is disseminated when the other person inhales them.

What transpires if you have TB?

Feelings of sickness or weakness, weight loss, a high temperature, and nocturnal sweats are some of the common signs of TB disease.

                          Coughing, chest pain, and the coughing up of blood are other signs of TB lung disease. Depending on the location affected, TB illness symptoms may manifest in various body parts.

The true statement on dilations are that :

Dilation is the process of increasing an object's size without altering its shape. Depending on the scale factor, the object's size may increase or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.

Dilation therefore allows for the same shape as the original shape, but it is a reduction of the original shape and so cannot be the same size.

$QS$ and $PR$ are parallel sides of the square, they have the same length, which is $10$. Therefore, we can conclude that $XM = NY = 10$.

Given the square $PQRS$ with side length $10$, the points $X$ and $Y$ are located outside the square such that $XQ < XS$ and $YR < YS$. We need to determine the relationship between the lengths of the segments $XY$, $QS$, and $PR$.

Since $XQ < XS$, we can conclude that $X$ lies between $Q$ and $S$. Similarly, since $YR < YS$, we can conclude that $Y$ lies between $R$ and $S$. Therefore, the segment $XY$ intersects the segments $QS$ and $PR$.

Let $M$ be the point of intersection between $XY$ and $QS$, and let $N$ be the point of intersection between $XY$ and $PR$. We can observe that $QS$ and $PR$ divide $XY$ into three segments: $XM$, $MN$, and $NY$.

Since $QS$ and $PR$ are parallel sides of the square, they have the same length, which is $10$. Therefore, we can conclude that $XM = NY = 10$.

In summary, we have $XM = 10$, $MN$, and $NY = 10$.

The simple interest for 4 years is Rs 960 and at the end of 4 years, the total amount in the bank account is Rs 2160.

Simple interest is calculated by multiplying the principal amount (initial deposit) by the interest rate and the number of years. In this case, the principal amount is Rs 1200 and the interest rate is 20% per annum (or 0.20) and the number of years is 4.

Simple Interest = Principal x Rate x Time

Simple Interest = 1200 x 0.20 x 4 = 960

So the simple interest for 4 years is Rs 960

To calculate the total amount at the end of 4 years, we add the simple interest to the original deposit.

Total Amount = Principal + Simple Interest

Total Amount = 1200 + 960 = 2160

So, at the end of 4 years, the total amount in the bank account is Rs 2160

Therefore, the simple interest for 4 years is Rs 960 and at the end of 4 years, the total amount in the bank account is Rs 2160.

The formula for finding the volume of a triangular prims is:

0.5 * b * h * length, where b is the length of the base of the triangle, h is the height of the triangle and length is prism length.

So, let's substitute those variables with the base length, height length, and prism length

The base length is 6km, the height length is 8km, and the prism length is 9km

So, we get:

0.5 * 6 * 8 * 9

= 1/2 * 6 * 8 * 9

= 1/2 * 48 * 9

= 1/2 * 432

The solution of the linear equation 3(x - 6) - 8x = 2 + 5*(2x + 1) is x = -5/3

Here we want to solve the equation:

3(x - 6) - 8x = 2 + 5*(2x + 1)

First, simplify both sides:

3x - 18 - 8x = 2 + 10x + 5

-5x - 18 = 10x + 7

Now group like terms:

-18 - 7 = 10x + 5x

Answer: a = (V^2 - v^2)/2s

Step-by-step explanation:

The equation for the final velocity is:

V^2 = v^2 + 2*a*s

where V is the final velocity, v is the initial velocity, a is the acceleration and s is the distance.

Now, we want to solve this formula for a, this would mean isolate a in one side of the equation, this is pretty simple, first we pass subtract v^2 in both sides.

V^2 - v^2 = v^2 + 2*a*s - v^2

V^2 - v^2 = 2*a*s

now we can divide by 2*s in both sides:

(V^2 - v^2)/2s = 2*a*s/2s = a

a = (V^2 - v^2)/2s
