The measures of the angles, obtained using circle theorems are;

a = 90°, b = 12°, c = 64°, d = 54°, e = 54°, f = 48°, g = 66°, h = 32°, i = 36°, and j = 20°

Circle theorems are theorems that specify the relationships between the chords, tangents, sectors, and angles in a circle.

The linear pair angles ∠a indicates;

a + a = 2·a = 180°

a = 180°/2 = 90°

The 78° angle in the inscribed right triangle indicates;

∠b = 90° - 78° = 12°

The 32° angle at the circumference of one of the circles indicates;

Angle at the center, which nis a base angle of the large triangle = 2 × 32° = 64°

A base angle of the large triangle = 64°

∠C = A base angle of the large triangle = 64°

2·c + d = 180° (Properties of a cyclic quadrilateral)

Therefore;

2 × 64° + d = 180°

d = 180° - 2 × 64° = 54°

d = 54°

Angle ∠e = Angle ∠d = 54°

The vertex angle of the inscribed isosceles triangle in the circle with angle ∠f is; 4·b

Therefore;

The vertex angle = 4 × 12° = 48°

An angle formed between a chord and a circle is equivalent to the angle in the segment that is in the alternate side or area, therefore;

Circle theorem indicates; ∠f = The vertex angle = 48°

The base angles of the isosceles triangle = (180° - 48°)/2 = 66°

Angle ∠g = 66°

The  chord which is the base of the isosceles triangle in the circle with the angle h forms an isosceles triangle with the sides of the large triangle, such that the base angles are also ∠c = 64°

Circle theorem indicates that the vertex angle of the triangle with angle h is also 64°

Therefore, according to circle theorem; 2·h = 64°

h = 64°/2 = 32°

The vertex angle of the quadrilateral with angle 2·f is; 180° - 2·f

The vertex angle is therefore; 180° - 2 × 48° = 84°

The angle at the center is therefore; 2 × 84° = 168°

Angle ∠i is therefore;

i = 360° - 5·b - 2·f - 168°

i = 360° - 5 × 12° - 2 × 48° - 168° = 36°

5·b + 2·h + i + j = 180°

Therefore; j = 180° - (5·b + 2·h + i)

j = 180° - (5 × 12° + 2 × 32° + 36°) = 20°

One possible solution to the linear equation −5x+y=−10 is:

x = 2

y = 0

To check if this solution is valid, we can substitute the values of x and y into the equation and see if it satisfies the equation:

(-5)(2) + (0) = -10

-10 = -10

Since the equation is true, we have found a valid solution.

From the given situation of equation Diamond worked 24 overtime hours that week.

The hourly rate that is paid for the typical hours worked within a pay period is known as regular pay. For full-time employees in the US, this is typically referred to as 40 hours a week. On the other hand, overtime pay is the hourly rate paid for any additional hours worked. Most businesses give time-and-a-half (1.5 times the usual pay rate) or double-time (two times the regular pay rate) for extra hours, which is often more than regular compensation.

Let us suppose the number of hours = x.

Let us suppose the overtime hours = y.

From the given situation we have:

7.5x + 11.25y = 352.5 (equation 1)

x + y = 35 (equation 2)

Substituting equation 2 into equation 1 and simplifying:

7.5x + 11.25(35 - x) = 352.5

7.5x + 393.75 - 11.25x = 352.5

-3.75x = -41.25

x = 11

Substitute the value of x = 11.

11 + y = 35

y = 24

Hence, Diamond worked 24 overtime hours that week.

to write the proportion is a number of the girl in intramural sport is [tex]\frac{x}{y} 2/3=230[/tex]

and find the number a girl in intramural sport is 90

Step-by-step explanation:

Please when you come across any questions including two equations of two variables, please solve that question by using the simultaneous method.

To go about that, since you would be given two equations, name one equation as "equation one" (eq 1) and the other, "equation two" (eq 2).

Right after that, make any of the variables a subject ( make it stand alone or be on one side of the equal to sign). Now, substitute that variable you've made the subject into the other equation which you didn't make any variable the subject. Solve for that, by grouping all like terms and you would realize that the final result would be the answer of one of the variables.

After getting that value, substitute that value in place of its variable. (For instance, x = 1, substitute the value which is 1 in place of x in the equation you made a variable the subject at the beginning). Solve for that equation too, and finally you would arrive at an answer or a value.

To verify that your answers are right, substitute the values in their respective variables. ( For instance, if x = 1 and y = 2, put 1 in place of x and 2 in place of y in the first equation then do same for the second equation as well). The answer would be the same as the number it has been equated to.

The length of the radius and diameter are 10.5 and 21 respectively

The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units like cm² and m². Area of a shape is a two dimensional quantity.

The area of the sector = tetha/360 × πr²

= 72/360 × 3.14 × r²

= 0.628r²

area of the circle = area of the shaded part + area of sector

3.14r² = 277 + 0.628r²

3.14r²-0.628r² = 277

2.512 r² = 277

r² = 277/2.512

r² = 110.3

r = √ 110.3

r = 10.5

d = 2r

d = 10.5 × 2

= 21

To find the percent increase in price, we need to calculate the difference between the original price and the new price, and then express that difference as a percentage of the original price.

The original price of the sweatshirt was $40, and the new price is $65, so the difference is:

$65 - $40 = $25

To express this as a percentage of the original price, we divide the difference by the original price and multiply by 100:

($25 / $40) x 100% = 62.5%

Therefore, the percent increase in the price of the sweatshirt is 62.5%.
