Find the area of the square

Find the area of the circle

Subtract the area of the circle from the area of the square.

area of square = 10 x 10 = 100 sq. Cm

Area of circle = pi x r ^2 = 3.14 x 5^2 = 78.5 sq. Cm

area of shard region = 100 - 78.5 = 21.5 cm^2

Answer:

that is a example of division problem if u have any other questions about division just ask I will help u the best I can

Step-by-step explanation:

Technically any two numbers in a ratio that are divisible by the other ratio numbers make them equivalent.

For instance,

[tex]3:6[/tex]

[tex]6:12[/tex]

[tex]Equivalent.[/tex]

Because...

[tex]\frac{3 * 2 = 6}{6 * 2 = 12}[/tex]

Or...

[tex]\frac{3}{6} = \frac{6}{12}[/tex]

The equation above represents, "Divide 3 by 6 and divide 6 by 12". From both equations to here, you now know what to multiply the numbers by to get your answer.

From here, multiply 3 by 2, and, 6 by 2, to get the equivalent ratio, 6:12.

Therefore, 6:7 and 24:28 are equal as 6:7 and 24:28 are, too.

Step-by-step explanation:

Answer:

the answer is 35.2101 explained in image .

Answer:

This is ratio. A:B = 3:5

If the 3 parts of a =90 that means 1 part =30 (90/3=30).

So B =5.

5 parts would equal 30x5= 150

B=150cm

The properties of the quadrilaterals gives the equivalent relations used

to find the lengths and the angles.

Response:

1. m∠AED = 90°

2. m∠ADE = 23°

3. m∠BAE = 67°

4. AE = 5

5. BE = 12

6. 19

7. 22

8. WXYZ is a rectangle

9. WXYZ is a square

10. [tex]\overline{QS} \cong \overline{RT}[/tex] by Corresponding Parts of Congruent Triangles Congruent, CPCTC

11. a. The diagonals are perpendicular and the given figure is not a rectangle

b. The given figure is not a rhombus

c. The figure is a square.

d. ∠AEB = 90°

e. m∠EAD = 45°

1. The  diagonals of a rhombus bisect each other at right angles

Therefore;

m∠AED = 90° (by definition of right angles)

2. m∠EAD and m∠ADE are complementary angles

Which gives;

m∠EAD + m∠ADE = 90°

m∠ADE = 90° - m∠EAD

Therefore;

m∠ADE = 90° - 67° = 23°

3. The diagonals of a rhombus bisect the angles, therefore;

m∠BAE = m∠EAD = 67°

4. The diagonals bisect each other, therefore;

AE = CE = 5

5. BE = DE = 12

6. JL = 3·x + 4

KM = 4·x - 1

Which gives;

3·x + 4 = 4·x - 1

4·x - 3·x = 4 + 1 = 5

x = 5

KM = JL = 3 × 5 + 4 = 19

7. JL = 2·x - 6

[tex]KM = \mathbf{\dfrac{3}{2} \cdot x+ 1}[/tex]

Which gives;

[tex]\frac{3}{2} \cdot x+ 1 = 2\cdot x - 6[/tex]

[tex]2\cdot x -\frac{3}{2} \cdot x = 6 + 1 = 7[/tex]

[tex]\dfrac{1}{2} \cdot x = 7[/tex]

x = 2 × 7 = 14

JL = 2 × 14 - 6 = 22

8. W(3, 1), X(3, -2), Y(-5, -2), Z(-5, 1)

WX = 1 - (-2) = 3

YZ = 1 - (-2) = 3

XY = 3 - (-5) = 8

WZ = 3 - 5 = 8

Slope of WX = (1 - (-2)) ÷ (3 - 3) = ∞

Slope of YZ = (1 - (-2)) ÷ (-5 - (-5)) = ∞

Slope of XY = (-2- (-2)) ÷ (3- (-5)) = 0

Slope of WZ = (1- 1) ÷ (3- (-5)) = 0

Therefore;

WX and YZ are perpendicular to XY and WZ

The properties of WXYZ are the properties of a quadrilateral having perpendicular sides.

9. W(4, 1), X(1, 4), Y(-2, 1), Z(1, -2)

WX = √((4 - 1)² + (1 - 4)²) = 3·√2

YZ = √((1 - (-2))² + (-2 - 1)²) = 3·√2

XY = √((1 - (-2))² + (4 - 1)²) = 3·√2

WZ = √((1 - (-2))² + (4 - 1)²) = 3·√2

Slope of WX = (4 - 1) ÷ (1 - 4) = -1

Slope of YZ = (-2 - 1) ÷ (1 - (-2)) = -1

Slope of XY = (1 - 4) ÷ ((-2) - 1) = 1

Slope of WZ = (-2 - 1) ÷ (1 - 4) = 1

Therefore;

The lengths of the sides are equal and the sides are perpendicular to each other

Therefore;

11. The properties of a rectangle are;

The interior angles are 90°

The diagonals are not perpendicular to each other

In the given figure, the four triangles formed by the diagonals are congruent, therefore;

The angles at the vertex point of the four tringles are equal to each other and therefore, equal to 90°

Therefore;

b. The lengths of the diagonals, are equal, therefore;

e. The properties of the figure, which includes;

All sides are equal

The interior angles are 90°

d. The diagonals of a square are angle bisectors of the interior angles

Therefore;

m∠ABE = m∠CBE

m∠ABE + m∠CBE = 90° by definition of complementary angles

Therefore;

m∠ABE  = 90° ÷ 2 = 45°

Similarly;

m∠ABE = m∠BAE = 45°

m∠AEB = 180° - (m∠ABE + m∠BAE)

e. m∠EAD = m∠BAE = 45° (angles formed by the diagonal AC)

The angles are 81 degrees and 99 degrees

============================================================

Explanation:

Consecutive angles, aka adjacent angles, of a parallelogram always add to 180 degrees. They are considered supplementary.

(angle A)+(angle B) = 180

(3x+42)+(9x-18) = 180

(3x+9x)+(42-18) = 180

12x+24 = 180

12x = 180-24

12x = 156

x = 156/12

x = 13

We can then find the measure of each angle

Then notice that A+B = 81+99 = 180 to confirm the answers.

Answer:

25/9 is the answer

the ratio of the area of PQSR to the area of FGHI is 25/9. The correct answer is:

25/9

To find the ratio of the area of quadrilateral PQSR to the area of quadrilateral FGHI, we can use the property that the ratio of the areas of two similar figures is the square of the ratio of their corresponding side lengths.

Given that quadrilateral PQSR is similar to quadrilateral FGHI, we know that the ratio of corresponding side lengths is QSGH = 5/3.

Now, let's find the ratio of the areas:

Ratio of areas = (QSGH)² = (5/3)² = 25/9

So, the ratio of the area of PQSR to the area of FGHI is 25/9. The correct answer is:
