Answer:

∠ B ≈ 66.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosB = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{2}{5}[/tex] , then

∠ B = [tex]cos^{-1}[/tex] ( [tex]\frac{2}{5}[/tex] ) ≈ 66.42° ( to the nearest hundredth )

Answer:

{ x | x < 2 or x > 8}

Step-by-step explanation:

Given the expression

(x + 3 < 5) U (x - 7 > 1).

Solve x+3 < 5

Subtract 3 from both sides

x+3 - 3 < 5-3

x < 2

For x - 7 > 1

Add 7 to both sides

x-7+7 > 1 + 7

x > 8

Hence the union of both is { x | x < 2 or x > 8}

Answer:

Step-by-step explanation:

It is hard to read but (5x - 2) + (7x - 9)  =  AC    also  5x - 2   =   7x - 9

    5x - 2 = 7x - 9         subtract 5x from both sides then add 9 to both sides

5x - 5x - 2 + 9  = 7x - 5x - 9 + 9

   -2 + 9 = 7x - 5x

          7  =  2x

        3.5  =  x

    5x - 2 = 7x - 9    

         3   ≠    -2                        when x = 1

         8   ≠     5                        when x = 2

        13   ≠    12                        when x = 3

     15.5   =    15.5                     when x = 3.5

        18   ≠    19                        when x = 4

Answer:

x = 15

Step-by-step explanation:

The right angle is formed at at the tangent line and the radius

So to solve for the missing angle we can solve for x using the Pythagorean Theorem

The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared

Knowing this we can create an equation to solve for x

[tex]12^2+9^2=x^2[/tex]

now we solve for x

[tex]12^2=144\\9^2=81\\81+144=225\\225=x^2\\\sqrt{225} =15\\\sqrt{x^2} =x\\x=15[/tex]

So we can conclude that x = 15

Step-by-step explanation:

Answer:

a. n=8

Step-by-step explanation:

to solve an equation, we must do the same operations to both sides.

step 1- add 8 to both sides. now n/4-8=-6 becomes n/4=2

step 2- multiply both sides by 4. so n/4=2 becomes n=8, which gives us our answer.

Answer:

Any choice that has a slope of -1/2

Step-by-step explanation:

-2x - 4y = 3

-4y = 2x + 3

4y = -2x - 3

y = -1/2x -3/4

y = mx + b

m = slope

Answer:

Step-by-step explanation:

Part A

Since, BDFHJ is a regular pentagon,

Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]

= [tex]\frac{(5-2)\times 180}{5}[/tex]

= 108°

Since, ∠ABC ≅ ∠JBD [Vertical angles]

Therefore, m∠ABC = m∠JBD = 108°

Part B

m∠JBD + mCBD = 180° [Linear pair of angles]

108° + m∠CBD = 180°

m∠CBD = 180 - 108

m∠CBD = 72°

Similarly, m∠BDF + m∠CDB = 180°

m∠CDB + 108° = 180°

m∠CDB = 180 - 108

             = 72°

In ΔCBD,

m∠BCD + m∠CDB + m∠DBC = 180°

m∠BCD + 72° + 72° = 180°

m∠BCD = 180° - 144°

              = 36°

Answer:

$68000

Step-by-step explanation:

Tax free earning = first 4000

Tax on remaining amount = 25%

Total earning in other to have $20000 net of tax earning :

Net of tax = tax free earning + (25% * remaining amount)

Let remaining amount = x

20000 = 4000 + (0.25 * x)

20000 = 4000 + 0.25x

20000 - 4000 = 0.25x

16000 = 0.25x

x = 16000 / 0.25

x = 64000

Hence,

Total earning should be :

Tax free earning + roaming amount

4000 + 64000

= $68000

Answer:

[tex]y-4=3(x-4)[/tex]

Step-by-step explanation:

Point-slope form is represented by the formula [tex]y-y_1 = m (x-x_1)[/tex]. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula for real values in order to write the equation of a line in point-slope formula.  

[tex]m[/tex] represents the slope, thus substitute 3 for it. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects. So, use the x and y values of the point (4,4) for the formula. Substitute 4 for [tex]x_1[/tex] and 4 for [tex]y_1[/tex]. This gives the following answer and equation in point-slope form:

[tex]y-4=3(x-4)[/tex]

Answer:

118

Step-by-step explanation:

the length ED is equal to EC

so

the angle is also the same

that's mean the angle ECD is equal to 31

then to find the another angle just do like this

=180–31–31

=118

Answer:

∠AEB = 118°

Step-by-step explanation:

∠EDC = 31°

∠ECD = ∠EDC = 31°

ΔDEC = contains 180°

∠DEC = 180 - 31 - 31 = 118°

∠AEB = 118° because it is a vertical angle to ∠DEC

Answer:

$20

Step-by-step explanation:

3 pounds of beef is 6 dollars.

6 divided by 3 is 2. Therefore, each pound cost $2.

He wants to buy 10 pounds of beef.

9 pounds would be $18.

Add 1 pound, which is $2 and you will get $20.

Therefore, he would pay $20!~

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

Explanation:

We will use the slope formula

m = (y2-y1)/(x2-x1)

Plugging in the given items leads to

-5 = (g-8)/(6-4)

Now solve for g

-5 = (g-8)/(6-4)

-5 = (g-8)/2

-5*2 = g-8

-10 = g-8

-10+8 = g

-2 = g

g = -2

We have (6,g) turn into (6,-2)

The two points (4,8) and (6,-2) are on a line of slope -5.

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

As a way to check, we'll find the slope of the line through (4,8) and (6,-2)

m = (y2-y1)/(x2-x1)

m = (-2-8)/(6-4)

m = -10/2

m = -5

The answer is confirmed.

Answer:

84 inches squared

Step-by-step explanation:

perimeter = 6+7+5+10+15

= 43

Answer:

Step-by-step explanation:

if you add all the angles in a triangle together, its 180 degrees.

so, (3x+2)+(4x+1)+(2x+1) = 180

we can combine like terms so 9x+4=180

                                                    9x=176

                                                       x=19.6 degrees

now plug the x into each angle and that's them
