The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides.
40
What is the measure of an interior angle?

Answers

Answer:

The polygon has 9sides with an interior angle measure of 140°

Step-by-step explanation:

The exterior angle of a regular polygon=360°/n

40°=360°/n

n=360°/40°=9

So the polygon has 9 sides thus, a nonagon.

The measure of the interior angle=(n-2)180°/n

=(9-2)×180°/9=140°

Answer:

x=4

y=6

Step-by-step explanation:

We need to find value of x and y if RS bisects AB and RS = 28

We are given: RS = 28

and We can see from figure that: RT= 3y-7 and TS = 2y+5

And we can observe that RT + TS = 36

So, putting all the values, we can find value of y

[tex]3y-7+2y+5=28[/tex]

Solving this equation, will find value of y

[tex]3y+2y+5-7=28\\5y-2=28\\5y=28+2\\5y=30\\y=\frac{30}{5}\\y=6[/tex]

So, we get value of y: y=6

Now, we also know that RS bisects the line AB. It means it divides both the lines equally.

So, we can write: AT = TB

Putting values we can find value of x

We have AT = 4x-2

TB = 4y+2

and y =6

[tex]4x-2 = 4y+2\\4x-2=4(6)+2\\4x-2=12+2\\4x=14+2\\4x=16\\x=\frac{16}{4}\\x=4[/tex]

So, we get value of x: x=4

pleasee help !!! finding equation of the image

Answers

Answer:

Step-by-step explanation:

Here, we want to write the final formula for the equation after performing the given transformations

Reflection on the y-axis means the x-axis value will change sign

that will give:

y = -x^1/3

Transition of 3 units in the positive x axis

mathematically, we are adding 3 to x

so we have

y = -(x+3)^1/3

4 units in the negative y direction means we are subtracting 4 from the whole equation

That means;

y = -(x + 3)^1/3 - 4

This shows that the first option is right

© Angad and Nick win some money and share it in the ratio 5:1. Angad gets £60 more than Nick.
How much did Nick get?

Answers

Answer:

£15

Step-by-step explanation:

Angad : Nick = 5 : 1

Let

Nick share = x

Angad share = x + £60

Angad : Nick

5 : 1 = x + £60 : x

5/1 = x + 60 / x

Cross product

5 * x = 1 * x + 60

5x = x + 60

5x - x = 60

4x = 60

x = 60/4

x = 15

If 5e = 45, then what does 7e equal?

Answers

45/5 = 9
e = 9

7 x 9 = 63

7e = 63

Answer:

7e = 63

Step-by-step explanation:

5e = 45

divide by 5 on both sides

5e/5 = 45/5

e = 9

So all you have to do is multiply 7 by 9 since ur substituting the x with ur answer

7(9) = 63

7e = 63

From the figure given we are told that ABC ~ DEC. Hence to get the value of x we will use the relationship shown;

25/3x-2 = 20/2x

Cross multiply

25(2x) = 20(3x - 2)

50x = 60x - 40

50x - 60x =-40

-10x = -40

x = 4

Answer:

The coordinates of the point that makes the division in the given ratio is (0,3)

Step-by-step explanation:

Here, we want to find the point on the line segment that divides the line segment in the ratio 1:2

We simply use the internal division formula

That would be;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

m = 1 and n = 2

(x1,y1) = (4,9)

(x2,y2) = (-8,-9)

Substituting these values into the formula, we have;

2(4) + 1(-8)/(1 + 2) , 2(9) + 1(-9)/(2 + 1)

= (8-8)/3 , (18-9)/3

= (0,3)

Were you in the living room
Chillin' watchin' television?

Think I've figured out how
How to let you go and let communication die out

How to think about you without it rippin' my heart out
