NEED ANSWER ASAP! ON A TIMED TEST!Four Chords Are Drawn In The Figure Below, Creating A Quadrilateral

Answers

Answer 1

Answer:

21°

Step-by-step explanation:

<DCB = 3x + 8°

< DAB = 5x + 4°

Now

<DCB + <DAB = 180° { being opposite angles of cyclic quadrilateral }

3x + 8° + 5x + 4° = 180°

8x + 12° = 180°

8x = 180° - 12°

8x = 168°

x = 168° / 8

Therefore x = 21°

Hope it will help :)

Answers

Step-by-step explanation:

If m is parallel to n and one of its angle is 25

Therefore, the vertically opposite angle to angle of 25 is also equal to 25

Now, we have to find x

Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)

Therefore, x =155

Find the circumference of the circle. Use as part of the answer

Answers

Answer:

21.99115 ≈ 22 cm

Step-by-step explanation:

1) So basically in the problem, they give you 7 cm as the diameter.

2) The circumference formula is C = 2πr (if they give you a radius) or C = πd (In this case, this would be the formula to use.)

3) Plug in; C = π(7) = 21.99114858 ≈ 22 cm

A cylinder has a volume of 48 cubic cm. What is the volume of a cone with the same radius and height?

Answers

Answer:

16 cm^3

Step-by-step explanation:

The computation of the volume of a cone is shown below:

As we know that

The Volume of the cylinder is πr^h

And the volume of the cone is 1 ÷ 3 πr^h

Also the height and the radius is the same for both

so, the volume of the cone is

= 1 ÷ 3 × 48

= 16 cm^3

A temperature in degrees Fahrenheit is shown in expanded notation. ( 9 × 10 ) + ( 4 × 0.1 ) How is this temperature in degrees Fahrenheit written a numeral?

Answers

Answer:

90.4 degrees.

Step-by-step explanation:

(9 x 10) + (4 x 0.1)

= 90 + 0.4

= 90.4.

The Temperature in Fahrenheit  is 90.4 F.

What is Expanded form?

The division of numbers into groups according to place value, such as ones, tens, hundreds, thousands, ten thousand, and so forth, results in the expanded form of the number. The expanded version of the number is the one that is represented by the sum of each digit times its place value.

Given:

Expanded notation. ( 9 × 10 ) + ( 4 × 0.1 )

Now, simplifying the expression

= (9 x 10) + (4 x 0.1)

= 90 + 0.4

= 90.4.

Hence, the Temperature in Fahrenheit  is 90.4 F.

If lines a and b are parallel determine the value of x.

Answers

Answer:  x = 15

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

Work Shown:

If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.

Let's solve for x

4x-30 = 2x

4x-2x = 30

2x = 30

x = 30/2

x = 15

C. 15
The 2 angles are the same because they are alternate interior angles, so...
4x - 30 = 2x
4x = 2x + 30
2x = 30
X = 15

substitute this equation x+3y=18 & -x-4y=-25

Answers

Answer:

 {x,y} = {3/7,-43/7}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    x + 3y = -18

  [2]    -x + 4y = -25

Graphic Representation of the Equations :

   3y + x = -18        4y - x = -25  

 

 

Solve by Substitution :

// Solve equation [1] for the variable  x  

 

 [1]    x = -3y - 18

// Plug this in for variable  x  in equation [2]

  [2]    -(-3y-18) + 4y = -25

  [2]    7y = -43

// Solve equation [2] for the variable  y  

  [2]    7y = - 43  

  [2]    y = - 43/7  

// By now we know this much :

   x = -3y-18

   y = -43/7

// Use the  y  value to solve for  x  

   x = -3(-43/7)-18 = 3/7  

Solution :

{x,y} = {3/7,-43/7}

Answers

Answer:

Step-by-step explanation:

Don't use 0 as a substitute for θ.  0 is always 0.

cosθ = -5/(2√15)

secθ = 1/cosθ = -2√15/5

The exact value of sec θ is -8.6/5.

What is Trigonometry?

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Point(-5, -7).

Here, x= -5 and y= -7

So, r = √x² + y²

r= √(-5)²  + (-7)²

r= √25 + 49

r = √74

r= 8.6

So, sec θ= H/ B

              = r/x

              = 8.6/ (-5)

              = -8.6/ 5
