which statement is NOT true for isosceles trapezoids?
•diagonals are congruent.
•opposite angles are supplementary
•one diagonal forms two congruent triangles
•the diagonals form small triangles, and two of the triangles are congruent.

Answer:

Hello there, lol.

Adjacent = Opposite/ Tan(35)

Adjacent = 4.3

Answer:

4.28

Step-by-step explanation:

basically using the sine ratios :

a/sinA = b/sinB = c/sinC

so, let's call the known side a (3) and its opposing angle A (35 degrees).

and we know C is 90 degrees.

sin(90) = 1

b = the missing side AC.

and because the sum of all angles in a triangle is always 180 degrees, the missing angle B is

B = 180 - 90 - 35 = 55

AC/sin(55) = 3/sin(35)

AC = b = sin(55) × 3/sin(35) = 4.28

a little more practice and calculate also c that way :

3/sin(35) = c/1

c = 3/sin(35) = 5.23

Answer:

(5x+20)+(4x-11)=180(linear pair)

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

now,

(2y+19)+(5x+20)=180(co-interior angle)

2y+19+5×19+20=180

2y+134=180

2y=180

y=180/2

y=90

Answer:

A = 36 pi m^2 or approximately 113.04 m^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 6

A = pi 6^2

A = 36 pi m^2

Using the approximation of 3.14 for pi

A =113.04 m^2

Answer:

A≈113.1

Step-by-step explanation:

A=πr^2=π·6^2≈113.09734

Answer:

r = 55°, s = 25°, t = 30°

Step-by-step explanation:

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

Sum the 4 angles in the top quadrilateral and equate to 360

r + 100° + 110° + 95° = 360°

r + 305° = 360° ( subtract 305° from both sides )

r = 55°

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180° in the left triangle for s

s = 180° - (100 + 55)° = 180° - 155° = 25°

Similarly for the triangle on the right for t

t = 180° - 95 + 55)° = 180° - 150° = 30°

Answer:

Step-by-step explanation:

In quadrilateral ADEF

r + 95 +100 +110 = 360  {Sum of all angle of quadrilateral}

               r + 305 = 360

                        r = 360 -305

r = 55

In triangle AEC,

r + 95 + t = 180

55 + 95 + t = 180

    150 + t = 180

             t = 180 -150

t = 30

In triangle ABD,

r +s + 100 = 180

55 + s + 100 = 180

      s + 155 = 180

            s = 180 - 155

s = 25

I think 14n + 9

Step-by-step explanation:

since she got her first email in 9 days and got her second email 14 days later, and it continues to appear every 14 days.

so I think it must be 14n + 9

Answer:

No, Liam is wrong

Step-by-step explanation:

Amount invested by Florence = £200

Formula for compound interest = P * (1 + R / 100)^Time period

P = £200

R = 5%

Time period = 2

£200 * (1 + 5/100) ^ 2

=> £200 * 1.05^2

=>£200 * 1.1025

=> £220.5

So the interest = 220.5 - 220 = 20.5

20.5 ≠ 20

Therefore, Liam is wrong.

Hope it helps :)

Answer:

[tex]48\pi\\\approx 150.796[/tex]

Step-by-step explanation:

1.Approach

To solve this problem, find the area of the larger circle, and the area of the smaller circle. Then subtract the area of the smaller circle from the larger circle to find the area of the shaded region.

2.Find the area of the larger circle

The formula to find the area of a circle is the following,

[tex]A=(\pi)(r^2)[/tex]

Where (r) is the radius, the distance from the center of the circle to the circumference, the outer edge of the circle. ([tex]\pi[/tex]) represents the numerical constant (3.1415...). One is given that the radius of (8), substitute this into the formula and solve for the area,

[tex]A_l=(\pi)(r^2)\\A_l=(\pi)(8^2)\\A_l=(\pi)(64)[/tex]

3.Find the area of the smaller circle

To find the area of the smaller circle, one must use a very similar technique. One is given the diameter, the distance from one end to the opposite end of a circle. Divide this by two to find the radius of the circle.

8 ÷2 = 4

Radius = 4

Substitute into the formula,

[tex]A_s=(\pi)(r^2)\\A_s=(\pi)(4^2)\\A_s=(\pi)(16)[/tex]

4.Find the area of the shaded region

Subtract the area of the smaller circle from the area of the larger circle.

[tex]A_l-A_s\\=64\pi - 16\pi\\=48\pi[/tex]

[tex]\approx150.796[/tex]

Answer:

B

Step-by-step explanation:

Answer:

x = 15

Step-by-step explanation:

Angles in a triangle add up to equal 180

Hence, 3x + 5x + 4x = 180

( Note that we've just created an equation that we can use to solve for x)

We now solve for x using the equation created

3x + 5x + 4x = 180

Combine like terms

12x = 180

Divide both sides by 12

x = 15

Answer:

x = 15

Step-by-step explanation:

The sum of the angles of a triangle is 180

3x+4x+5x = 180

Combine like terms

12x = 180

Divide by 12

12x/12 =180/12

x = 15

Answer:

x =3 and y =1

Step-by-step explanation:

( x+y , x-2y) = (4 , 1)

compare their corresponding elements

x+y = 4

y = 4 - x         equation (i)

x-2y =1

substitute the value of x

x - 2(4 - x) =1

x - 8 + 2x =1

3x = 1 +8

x = 9/3

x = 3

Now substitute the value of x in equation (i)

y = 4 - x

y = 4 - 3

y = 1

Answer:

x = 3, y = 1

Step-by-step explanation:

Equate the x and y coordinates of the given points

x + y = 4 → (1)

x - 2y = 1 → (2)

Subtract (2) from (1) term by term to eliminate x

0 + y - (- 2y) = 4 - 1

y + 2y = 3

3y = 3 ( divide both sides by 3 )

y = 1

Substitute y = 1 into (1) for corresponding value of x

x + 1 = 4 ( subtract 1 from both sides )

x = 3

Answer:

12.56 in ^2

Step-by-step explanation:

First find the area of a circle with radius 4

A = pi r^2

A = (3.14) 4^2

A =50.24

Since it is 1/4 of a circle, multiply by 1/4

1/4 ( 50.24)

12.56

Answer:

Quarter circle's area is 12.56 inches².

Step-by-step explanation:

Concept:- Firstly, we need to find the area of circle and Since, it is quarter of circle we need to multiply the area of circle by 1/4. and we get answer

Finding area of circle

Using Formula

Area of circle = π × r ²

Where,

And we have given

Substitute the value into the formula

Area of circle = 3.14 × ( 4 in. )/²

now,

Area of circle = 3.14 × 16 in ².

multiply , we get

Area of circle is 50.24 nches ²

As have to find the quarter circle's area ,

and we know that quarter is the one fourth of the circle .

Quarter circle's area = Area of circle × 1/4

Multiply , we get

Quarter circle's area = 50.24 × 1/4

Therefore, quarter circle's area is 12.56 inches².

Answer:

(x, y) = (10, 290)

Step-by-step explanation:

From the table

Total fees = fixed + variable

Fixed:

When number of times Ahmed mowed, x = 0

y = 40

When x = 2, y = 65

Rate of change = y2 - y1

= 65 - 40

= 25

y = 40 + 25x

Where,

y = total fees charged

40 = fixed fee

25x = variable fee

Total amount Ahmed will make for mowing 10 times

when x = 10

y = 40 + 25x

y = 40 + 25(10)

= 40 + 250

= 290

y = 290

(x, y) = (10, 290)
