The angle measurements in the diagram are represented by the following expressions.
A = 8x+ 78°
B = 2x + 114
B=

Answers

Since angle A and B are interior angles, we can set them equal to each other. So then we can solve for x and plug x in for B.
1) 8x + 78 = 2x + 114
2) 8x - 2x = 114 - 78
3) 6x = 36
4) 6x / 6 = 36 / 6
5) x = 6
Now we can plug in x to equation b
1) 2(6) +114
2) angle b = 126

Answer:

C = 39

Step-by-step explanation:

From the question given above, the following data were obtained:

A = 2x + 108

B = x + 33

C =?

Next, we shall obtain an expression for C. This can be obtained as follow:

A + B + C = 180 (sum of angles in a triangle)

2x + 108 + x + 33 + C = 180

2x + x + 108 + 33 + C = 180

3x + 141 + C = 180

Make C the subject by rearranging

C = 180 – 141 – 3x

C = 39 – 3x

Next, we shall determine the value of x. This can be obtained as follow:

A = 2x + 108

B = x + 33

C = 39 – 3x

A + B + C = 180

2x + 108 + x + 33 + 39 – 3x = 180

2x + x – 3x + 108 + 33 + 39 = 180

3x – 3x + 180 = 180

3x – 3x = 180 – 180

3x – 3x = 0

x(3 – 3) = 0

x(0) = 0

x = 0

Finally, we shall determine C. This can be obtained as follow:

C = 39 – 3x

x = 0

C = 39 – 3(0)

C = 39 – 0

C = 39

The total cost of these 2 pens is 60p.
Work out the total cost of 5 of these pens.
Give your answer in pounds.

Answers

150p

To find the cost of one pen, do 60/2

So 30p/ pen

Just multiply this value by 5 :)

30 x 5= 150

Answer:

£1.50

Step-by-step explanation:

If two pens equal 60p

do 2 x 2 = 4

4 pens equal £1.20

to get 1 pen do 60p divided by 2

which equals 30p

now add £1.20 and 30p

The circumference of a circle is 7π m. What is the area, in square meters? Express your answer in terms of π

Answers

Answer:

[tex]12.25\pi\,\,m^2[/tex]

Step-by-step explanation:

Given: Circumference of a circle = [tex]7\pi\,\,m[/tex]

To find: Area of a circle in terms of [tex]\pi[/tex]

Solution:

Let r denotes radius of a circle.

Circumference of a circle = [tex]2\pi r[/tex]

[tex]7\pi=2\pi r\\7=2r[/tex]

Divide both side by [tex]\pi[/tex]

[tex]3.5\,m=r[/tex]

Area of a circle = [tex]\pi r^2[/tex]

Put [tex]r=3.5\,\,m[/tex]

[tex]=\pi (3.5)^2\\=12.25\pi\,\,m^2[/tex]

Answer:

A ≈ 3.9

Step-by-step explanation:

How to solve

Using the formulas

A=πr2

C=2πr

Solving for A

A=C2

4π=72

4·π ≈ 3.8993

Therefore, the circle in square meters in the nearest tenths is A ≈ 3.9

The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.

Answers

Answer:

the sum of exterior angle of a polygon is always 360 degree.

therefore,

xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°

40x = 360°

x = 360/40 = 9

x = 9

The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9

The exterior angles of the polygon are given as:

xº, 2x°, 4x°, 6x°, 8x°, 9x° and 10x°

The exterior angles of a polygon add up to 360 degrees.

So, we have:

[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]

Evaluate like terms

[tex]40x\° = 360\°[/tex]

Divide both sides of the equation by 40

[tex]x\° = \frac{360\°}{40}[/tex]

Divide 360 by 40

[tex]x\° = 9[/tex]

Rewrite as:

[tex]x = 9\°[/tex]

Hence, the value of x is 9

Answers

Answer: The angle C measures 120 degrees.

Step-by-step explanation:

For a polygon of n side, the sum of internal angle, in degrees is given by:

S = (n - 2) x 180

Parallelogram

4 sides, so

S = ( 4 - 2) * 180 = 360

Two pair of equal angles

B and D measure 60

A and C measure x. so

2ₓ + 2 * 60 = 360

2× = 240

× = 240/2

× = 120

The angle C measures 120 degrees

Answers

Answer:

Yes, each x-value is paired with exactly one y-value (no more than that)

Domain: x = -2, x = 1, x = 4, x = 7

No, the inverse is not a function, the x value of 6 would be paired with two y values (-2 and 7)
