The measure of the missing angle in a given pentagon is 115°. Therefore, option A is the correct answer.

The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

2) The sum of the interior angles of a nonagon

Here, n=9

(9-2)×180°

= 1,260°

3) Here, ∠3+∠4=180°

∠3=101°

101°+∠4=180°

∠4=79°

So, option A is the correct answer.

4) Given that, a regular polygon with 12 sides.

Now, sum of the interior angles = (12-2)×180°

= 1800°

Measure of each angle = 1800/12

= 150°

5) Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°.

Let the measure of fifth angle be x°

85°+110°+135°+95°+x°=540°

425°+x°=540°

x°=115°

So, option A is the correct answer.

The measure of the missing angle in a given pentagon is 115°. Therefore, option A is the correct answer.

From the linear function that is represented by the table, we can conclude that the slope is -2, and the y-intercept is 12.

The linear function is an equation for a line that can be written by finding the slope between two points on that line, then finding the y-intercept by using the slope-intercept equation: y=mx+b, where b represents the y value of the y-intercept point.

Now we take a look at the following data:

X     Y

–3   18

0    12

3     6

6     0

We want to know the slope by picking two out of four given points, let's say we pick the first two points:

y - y₀ = m (x - x₀)

(18 - 12) = m (-3 - 0)

6 = m * -3

m = 6 / -3

m = -2

Thus the slope is -2.

Now we substitute the slope value to one of the points, let's say we pick the first point:

(x₀, y₀) = (-3, 18)

y - y₀ = m (x - x₀)

y - 18 = -2 (x - (-3))

y = -2x - 6 + 18

y = -2x + 12

Thus the y-intercept of the linear function is 12.

The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2.

The formula for finding the area of a triangle with an unknown height is: Area = (Base * Height) / 2. This formula uses the base length of the triangle, multiplied by the height of the triangle, then divided by 2. To use this formula, start by determining the base length of the triangle. This is the length of any one side of the triangle. Once the base is determined, use the formula to calculate the area. In the formula, the base is multiplied by the height of the triangle. Since the height is unknown, use the Pythagorean Theorem to calculate it. The Pythagorean Theorem states that the square of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Once the hypotenuse is known, the height can be found by using the formula (Height = Hypotenuse - Base) / 2.

A fixed point in the plane around which all points are enlarged or contracted is the centre of a dilation. The centre, which may be found within, outside, or on a figure, is the only invariant (not changing) point under a dilation (k 1).

A Dilation of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.

The scale factor determines how much the dilated image is enlarged or reduced in size in relation to the original. A positive scale factor is required. When the scale factor exceeds 1, the dilation becomes an expansion. If it falls within the range of 0 and 1, the dilation is a contraction.

The point from which the image is dilated is known as the centre of dilatation (or point of dilation).

Following are some shape characteristics that aren't altered by the dilation transformations:

Horizontal Dilation

The dilation transformation of a function y=f(x) is dilated horizontally by a scale factor C is

Y = f(Cx)

This kind of transformation is called a horizontal dilation.

Vertical Dilation

The dilation transformation of a function y=f(x) is dilated vertically by a scale factor C isY = C * f(x)

This kind of transformation is called a Vertical dilation.

The ratio of matching side lengths is the scale factor of a dilatation. The origin will always be the centre of dilatation in this course. You can enlarge a polygon by connecting its vertices while multiplying each vertex's coordinates by the scale factor k.

Answer:

325 adults and 612 students entered the school play

Step-by-step explanation:

1st equation: x is the number of adults and y the number of students.

2nd equation: Students times what they payed + adults times what they payed:

1st:          x + y = 937

2nd:       2x + 0.75y = 1109

x = 937 - y

Now let's replace x for (937 - y) in the 2nd equation, to find out the value of y:
2(937 - y) + 0.75y = 1109

1874 - 2y + 0.75y = 1109

1874 - 1.25y = 1109

-1.25y = 1109 - 1874

-1.25y = -765 (multiply -1)

1.25y = 765

y = 765 / 1.25

y = 612

Now that we found the y value, let's replace it in the 1st equation to find out the value of x:

x + 612 = 937

x = 937 - 612

x =  325

If you want to double check it, you can replace both in the 2nd equation, to make sure:
2 * 325 + 0.75 * 612 = 1109

650 + 459 = 1109  (checked)
