The angle be 5x - 12 and 3x - 8 then the value of x  = 25.

The angle created by the two rays or arms at a shared vertex is known as the angle measure in geometry.

Two straight lines or rays intersect at a same terminus to make an angle. The vertex of an angle is the point at which all points meet. Angle is derived from the Latin word angulus, which means "corner."

A protractor is a precision tool for measuring angles. Angles are measured in degrees, therefore the term "degree measure." Because one full revolution is equivalent to 360 degrees, it is divided into 360 segments.

Let the two angle be 5x - 12 and 3x - 8

5x + 3x - 12 - 8 = 180

Add similar elements: 5x + 3x = 8x

8x - 12 - 8 = 180

Subtract the numbers: -12 - 8 = -20

8x - 20 = 180

Move 20 to the right side

8x = 200

Divide both sides by 8

= 8x / 8 = 200 / 8

x  = 25

Therefore, the value of x  = 25.

the pairs of ratios that form a true proportion: a and b

An equation proving the equality of two ratios is a genuine proportion. Knowing one ratio in a percentage can be used to determine values in the other equal ratio.

Where x is the number of successes and n is the sample size, p′ = x / n. The variable p′ represents the proportion of the sample and acts as a point estimate for the proportion of the genuine population.

Now, given that -

a. 3:6 and 5:10

= 1:2 and 1:2

Thus, it is a true proportion.

b. 4/12 and 6/18

= 4:12 and 6:18

The size of each exterior angle is given by β = 180° - θ.

To find the size of each interior angle of a regular polygon you need to find the sum of the interior angles first.

If the number of sides is n, then the sum of the interior angles is:

S = 180 (n-2)

This formula derives from the fact that if you draw diagonals from one vertex in the polygon, the number of triangles formed will be 2 less than the number of sides. Each triangle has 180°.

This form of the formula derives from drawing triangles in the polygon by drawing lines from a central point to each vertex. In this way the number of triangles is the same as the number of sides, but the angles at the centre are not required, so 360° is subtracted.

Once you have the sum of all the interior angles you divide by the number of sides to find the size of each interior angle.

Each interior angle of a regular polygon with n sides:

θ = 180°(n-2)/n

Each exterior angle of a regular polygon with n sides:

β = 180° - θ

Thus, the size of each exterior angle is given by β = 180° - θ.

Answer:

r90° (P) = (4, -5).

Step-by-step explanation:

The point P is (5, 4). To find the image of P after rotating it 90° counterclockwise, we use the transformation matrix for a 90° counterclockwise rotation:

[[0, -1], [1, 0]]

The coordinates of the image of P after rotating 90° counterclockwise are given by:

[[0, -1], [1, 0]] * [5, 4] = [4, -5]

So, r90° (P) = (4, -5).

The ratio of the area of circle A to the area of circle B expressed in the common fraction is 4/9.

An arc is a portion of the circumference of a circle. The length of an arc is proportional to the radius of the circle and the measure of the angle formed by the arc and the center of the circle. The formula for the length of an arc is:

Arc Length = (Angle Measure / 360) x (Circumference)

In this problem, we are given that the arc of 55 degrees on circle A has the same length as the arc of 40 degrees on circle B. So we can set up the following equation:

(55/360) x (Circumference of A) = (40/360) x (Circumference of B)

We can simplify this equation by canceling out the common factor of 360:

(5/12) x (Circumference of A) = (2/9) x (Circumference of B)

Now we can use the fact that the circumference of a circle is equal to 2π times the radius:

(5/12) x (2π x radius of A) = (2/9) x (2π x radius of B)

We can cross-multiply and divide by 2π to find the ratio of the radii of the two circles:

(5/12) x (radius of A) = (2/9) x (radius of B)

radius of A / radius of B = (2/9) / (5/12) = 12/18 = 2/3

Since the ratio of the areas of two circles is equal to the square of the ratio of their radii, the ratio of the area of circle A to the area of circle B is:

Area of A / Area of B = (radius of A / radius of B)^2 = (2/3)^2 = 4/9

So the ratio of the area of circle A to the area of circle B is 4/9.

The scale factor of the dilation transformation of the pre-image triangle ΔDEF to the image ΔD'E'F', with the origin as the center of dilation is 3.

A dilation transformation is one in which the lengths of the sides of the pre-image are scaled up by a common factor to get the lengths of the sides of the image.

The coordinates of the vertices of the triangle ΔDEF are;

D(1, 5), E(1, 2), F(3, 2)

The length of the sides of triangle ΔDEF, making use of the difference between the non equal coordinate points, are;

DE = 5 - 2 = 3

EF = 3 - 1 = 2

The length of the side DF can be found using the formula for the distance between two points on the coordinate plane (a form of the Pythagorean Theorem), which is presented as follows;

DF = √((3 - 1)² + (2 - 5)²) = √(2² + (-3)²) = √(13)

The coordinates of the vertices of triangle ΔD'E'F' are; D'(3, 15), E'(3, 6), F'(9, 6)

Therefore; D'E' = 15 - 6 = 9

E'F' = 9 - 3 = 6

D'F' = √((9 - 3)² + (6 - 15)²) = √(6² + (-9)²) = √(9 × 13) = 3·√(13)

The scale factor, s.f. = The ratio of the corresponding sides of the triangles which is found as follows;

D'E'/DE = 9/3 = 3

E'F'/EF = 6/2 = 3

D'F'/DF = 3·√(13)/√(13) = 3

Answer:

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

the ratio of the other 2 angles = 2 : 3 = 2x : 5x ( x is a multiplier )

sum the 4 angles and equate to 360

2x + 3x + 74 + 231 = 360

5x + 305 = 360 ( subtract 305 from both sides )

5x = 55 ( divide both sides by 5 )

x = 11

An equation is a claim that demonstrates the equality of two mathematical expressions, according to algebra. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

So, the sum of the exterior angles of a polygon with 15 sides is 2340 degrees.

The sum of the exterior angles of a polygon can be found using the formula: (n-2) * 180 degrees, where n is the number of sides of the polygon.

In the case of a polygon with 15 sides, the number of sides (n) is 15. Therefore, the sum of the exterior angles can be found by plugging in 15 for n and solving the equation:

(15-2) * 180 = (13) * 180 = 2340 degrees

Therefore, the sum of the exterior angles of a polygon with 15 sides is 2340 degrees.

It's worth noting that the sum of all exterior angles of a polygon is always 360 degrees less than the sum of the interior angles of a polygon.

The sum of the interior angles of a polygon with n sides is (n-2)*180.

So for a 15 sided polygon the sum of the interior angles is (15-2)*180 = 2340 degrees.
