Answer:

x = 47°

Step-by-step explanation:

First see that Angle W is 90°. Either because T is the center and LS is a diameter. Or because Arc LCS is 180° so Angle W is half that = 90°

Then, see Triangle WSL. The angles in a triangle add up to 180°

90° + x + x-4 = 180°

Subtract 90°

x + x - 4 = 90

Combine the x's

2x - 4 = 90

Add 4

2x = 94

Divide by 2.

x = 47

I'm not sure if you need to round to the nearest whole or hundreth or tenth

Answer:

no solutions

Step-by-step explanation:

x+y = 5

-2x-2y = 10

Multiply the first equation by 2

2x+2y =10

Add this to the second equation

2x+2y =10

-2x-2y =10

0 =20

This is not true so there are no solutions

The amplitude of a periodic graph of a function is 2 because the amplitude of the function is half of the difference between the maximum and minimum values of a function.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function(refer to attached picture)

We know the amplitude of the function is given by:

[tex]\rm Amplitude \ of \ f \ = \frac{1}{2} |max \ f -min \ f|[/tex]

As we can see in the graph the maximum value is 0 and

the minimum value of a function is -4, thus the amplitude

[tex]\rm Amplitude \ of \ f \ = \frac{1}{2} |0 -(-4)|[/tex]

The amplitude of f = 2

Thus, the amplitude of a periodic graph of a function is 2 because the amplitude of the function is half of the difference between the maximum and minimum values of a function.

Applying the angles of intersecting secants theorem, the measures of the arcs are:

m(KL) = 20°; m(MJ) = 80°.

When two secants intersect and form an angle outside the circle, the measure of the angle formed is half the positive difference of the measures of the intercepted arcs.

Given the following:

m∠MEJ = 1/2(MJ - KL)

30 = 1/2(MJ - KL)

60 = MJ - KL

KL = MJ - 60

m∠MFJ = 1/2(MJ + KL)

50 = 1/2(MJ + MJ - 60)

100 = 2MJ - 60

2MJ = 100 + 60

2MJ = 160

MJ = 160/2

MJ = 80°

KL = MJ - 60 = 80 - 60

KL = 20°

Thus, applying the angles of intersecting secants theorem, the measures of the arcs are:

m(KL) = 20°; m(MJ) = 80°.

Answer:

[tex]y=\frac{1}{10}x + 7[/tex]

Step-by-step explanation:

Hi there!

We are given the points (-20, 5) and (-10, 6)

We want to write the equation of the line in slope-intercept form

Slope-intercept form can be written as y=mx+b, where m is the slope, and b is the y intercept

First, let's find the slope of the line

The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex]and [tex](x_2, y_2)[/tex] are points

We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes

[tex]x_1=-20\\y_1=5\\x_2=-10\\y_2=6[/tex]

Substitute these values into the formula to find the slope

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{6-5}{-10--20}[/tex]

Simplify

m=[tex]\frac{1}{-10+20}[/tex]

m=[tex]\frac{1}{10}[/tex]

The slope (m) of the line is 1/10

We can substitute this value into the formula y=mx+b

y = [tex]\frac{1}{10}x[/tex] + b

Now we need to solve for b

As the equation passes through the points (-20, 5) and (-10, 6), we can use either point to solve for b.

Taking (-20, 5) for instance:

Substitute -20 as x and 5 as y:

5=[tex]\frac{1}{10}(-20)[/tex] + b

Multiply

5=-2+b

Add 2 to both sides

7=b

Substitute 7 as b.

y=[tex]\frac{1}{10}x + 7[/tex]

Hope this helps!

Answer: x=12

Step-by-step explanation:

The two angles provided are on a straight line

A straight line is 180 degrees, so we can add the two angles to make 180 and solve for x

[tex]10x-20+6x+8=180[/tex]

Simplify

[tex]10x-20+6x+8=180\\10x+6x-20+8=180\\16x-12=180[/tex]

Add 12 on both sides

[tex]16x-12=180\\16x-12+12=180+12\\16x=192[/tex]

Divide both sides by 16 to isolate x

[tex]16x=192\\\frac{16x}{16} =\frac{192}{16} \\x=12[/tex]

Answer:

2880 ft³

Step-by-step explanation:

T o find the total amount of water that is needed to fill the pool, you have to find the volume of the pool.

Formula to find the volume of a rectangle prism is :

Volume = length × width × height

Let us solve now.

Volume = length × width × height

Volume = 36 ft × 20 ft × 4 ft

Volume = 2880 ft³

Therefore, 2880 ft³ of water is needed to fill the pool.

Answer:

[tex]\implies m\angle A =42\degree[/tex]

Step-by-step explanation:

Quadrilateral ABCD is inscribed in circle with center O.

-> Quadrilateral ABCD is cyclic.

Opposite angles of a cyclic quadrilateral are supplementay.

[tex]\implies m\angle B + m\angle D = 180\degree[/tex]

[tex]\implies (2x)\degree + (3x-5)\degree = 180\degree[/tex]

[tex]\implies (5x-5)\degree = 180\degree[/tex]

[tex]\implies 5x-5= 180[/tex]

[tex]\implies 5x= 185[/tex]

[tex]\implies x= \frac{185}{5}[/tex]

[tex]\implies x= 37[/tex]

[tex]\implies m\angle A =(x+5)\degree[/tex]

[tex]\implies m\angle A =(37+5)\degree[/tex]
