Answer:

50

Step-by-step explanation:

Sum of angles in a circle is 360,

145 + 165 + x = 360

310 + x = 360

x = 360 - 310

x = 50

Answer:

[tex] {x}^{2} - 8x + 15 \\ (x - 5)(x - 3)[/tex]

I hope I helped you^_^

Answer:

(x-5) (x-3)

Step-by-step explanation:

At first find two numbers, that if you multiply, you get +15x², and the same number, if you do addition, get -8x

Those numbers are: -5x and -3x.

Now replace the -8x with the -5x and -3x. (x² - 5x - 3x + 15)

Now factorise as normal. You should get (x-5) and (x-3)

Hope I helped!

[tex]\frac{11\pi }{3}[/tex] ≈

11.519173063

Step-by-step explanation:

3[tex]\pi[/tex] + [tex]\frac{2\pi }{3}[/tex]

To add or subtract expressions, expand them to make their denominators the same. Multiply 3[tex]\pi[/tex] times [tex]\frac{3}{3}[/tex].

[tex]\frac{3 x 3\pi }{3}[/tex] + [tex]\frac{2\pi }{3}[/tex]

Since [tex]\frac{3x3\pi }{y3}[/tex] and [tex]\frac{2\pi }{3}[/tex] have the same denominator, add them by adding their numerators.

[tex]\frac{3 x 3\pi + 2\pi }{3}[/tex]

Do the multiplications in 3×3π +2π.

[tex]\frac{9\pi + 2\pi }{3}[/tex]

Combine like terms in 9π+2π.

Step-by-step explanation:

4x = 70 - x

4x + x = 70

5x = 70

x = 14

m∠DEA = m∠BEC = 4x

m∠DEA = m∠BEC = 4(14)

m∠DEA = m∠BEC = 56°

m∠AEB = m∠CED = [360 - 2(56)] ÷ 2

m∠AEB = m∠CED = [360 - 112] ÷ 2

m∠AEB = m∠CED = 248 ÷ 2

m∠AEB = m∠CED = 124°

Answer:

y = x² - 6x + 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (3, 0 ) , then

y = a(x - 3)² + 0

To find a substitute (1, 4) into the equation

4 = a(1 - 3)² = a(- 2)² = 4a ( divide both sides by 4 )

1 = a

y = (x - 3)² = x² - 6x + 9

Answer:

11.2 mi

Step-by-step explanation:

1. We can use the Pythagorean Theorem (a^2 + b^2 = c^2) to find the missing leg, b, of the triangle.

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 81 from both sides.

Step 3: Take the square root of both sides and round to the nearest tenth.

Therefore, x = 11.2 mi.

Answer:

lx-24l ≤ 8

Step-by-step explanation:

lx-24l ≤ 8

x ≤ 8 + 24

x ≤ 32

-----------------

-x + 24 ≤ 8

24 - 8 ≤ x

16 ≤ x

The absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.  

For example, |5| is 5 because it is 5 units away from 0.  Also, |-5| is also 5 because -5 is 5 units from 0.

We have been given that for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines.

To determine the absolute value equation that represents the minimum and maximum lengths.

First,  we need to find the difference between both solutions.

⇒ 32 - 16 = 16

Then, divide it by 2.

⇒ 16/2 = 8

⇒ 8 = |x - 32 + 8|

we could also write: 8 = |x - 32 + 8|

⇒ 8 = |x - 24|

Therefore, the absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

13.5÷5.99=2.25

Answer:

289 student for the party them one mother say where you went that their mother where you want a brother se usse lion and the world I say diesel OK will die and back

for vertical angles they're equal to each other.

thus,

(7x + 30)° = (11x - 24) °

54 = 4x

x = 13.5°

and

(17y - 4) ° = (5y + 38) °

12y = 42

y = 3.5°

Let width be x

ATQ

[tex]\\ \sf\longmapsto 2(x+4x)=70[/tex]

[tex]\\ \sf\longmapsto 5x=35[/tex]

[tex]\\ \sf\longmapsto x=7[/tex]

Step-by-step explanation:

The length of a rectangle is four times its width.

If the perimeter of the rectangle is 70 ft,

let the width =x

length =4width=4x

According to the question,

the perimeter of the rectangle is 70 ft

Therefore:-

width =x=7ft

length =4x=4×7=28ft

Answer:

63

Step-by-step explanation:

A median bisects the side that it is drawn to, so

So, FN = 4(15) + 3 = 63.

Once again, since a median bisects the side it is drawn to, NE = 63.

Answer:

x=25

Step-by-step explanation:

they are supplementary and adjacent, thus you do 4x-3+3x+8=180, simplify and get 7x+5=180, subtract 5 from 180 which is 175, then ending up with 7x=175 and 175/7 is 25.

Sum of the exterior angles of a pentagon = 360

              ⇒   115 + 2x + 3x + x + x = 360      

                                   [simplify the x terms and subtract 115 from both sides]

                                                  7x = 360 - 115   [divide both sides by 7]            

let the interior angles of the given triangle be angle a b c respectively.

116+a=180 (Sum of angles on a straight line.)

a=180-116

a=64

.......

112+b=180(Sum of angles on a straight line.)

Sum of angles on a straight line.)b=180-112

b=68

....

angle a +b+c=180 (Sum of angles of a triangle)

64+68+c=180

c=180-132

c=48

.,....

angle c +X =180(Sum of angles on a straight line.)

48+X=180

X=132

Therefore the value of X is 132.

2.

solution,

Let the remaining interior angle of the given triangle be y.

Then,

y+108=180(Sum of angles on a straight line.)

y=72

Again,

2x+X+y=180(Sum of angles of a triangle)

3x+72=180

3x=108

X=108÷3

X=36

Therefore the value of X is 36.

3.

solution,

let the remaining interior angle of the given polygon be a and b .

Then,

100+b=180(Sum of angles on a straight line.)

b=80

......

Again,

a+b+110+90=360(Sum of interior angle of the polygon)

a+80+200=360

a+280=360

a=80

.....

a+X=180(Sum of angles on a straight line.)

80+X=180

X=100

Therefore the value of X is 100.

4.

solution,

The given triangle is an isosceles triangle.So their base angles are equal .

43+43+X=180(Sum of angles of a triangle)

X=180-86

X=94

Therefore the value of X is 94.

5.

solution,

Opposite angles of a parallelogram is equal

So ,

X=125

Therefore the value of X is 125.

6.

solution,

Let the remaining interior angle of the triangle be a .

Then,

a+117=180 (Sum of angles on a straight line.)

a=63

Now,

a+X+83=180(Sum of angles of a triangle)

63+83+X=180

146+X=180

X=34

Therefore ,the value of X is 34.
