HOW CAN POSTULATES AND THEOREMS RELATING TO SIMILAR AND CONGRUENT ANGLES BE USED TO WRITE A PROOF?

Answer:

Step-by-step explanation:

Sum of digits of rank even - sum of digits of rank odd  must be a multiple of 11

(5+4+m+1)-(1+6+0)=11*k

10+m-7=11*k

3+m=11*k

m=8

Proof: 1086415/11=98765

Answer:

Step-by-step explanation:

There are two ways to do this.

Her current pay is C

Her previous pay is x

C = x + 7/100 * x

Or you could combine x and 7% of x immediately

7/100 x = 0.07x

C = 1.07 * x

Answer:

x times 107%

Step-by-step explanation:

If Mrs. Franklin received a 7% raise on x salary she would now be earning 7% more than x. To find this we can easily multiply x by 107% since she is earning 7% more than her previous salary, or x, and get our answer.

Answer:

The angles in the triangle and 10, 80 and 90

Step-by-step explanation:

The two angles that are left in a right triangle add to 90 degrees

8:1 means that there total is 9

8x+1x = 9x

9x = 90

Divide by 9

9x/9 = 90/9

x = 10

8*10 = 80

1*10 = 10

The angles are 80 and 10

The angles in the triangle and 10, 80 and 90

Answer:

n=6 u=28/3

Step-by-step explanation:

system of equations

The number of used books sold will be 7 and that of the new book will be 9.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given

Number of used books = u

Number of new books  = v

In the first case;

12u + 4n =  136

In the second case;

28u + 4n = 248

By both equations,

u = 7 and n = 9

So the number of used books is 7 and the new is 9.

Answer:

9

Step-by-step explanation:

r = 27/81 = 1/3

a = 81

Tn = 1/81

ar^(n-1) = 1/81

81(1/3)^(n-1) = 1/81

(1/3)^(n-1) = 1/6561

(1/3)^(n-1) = 1/3^(8)

Compare the exponents,

n-1 = 8

n = 9

Answer:

KM = 50 mm , ∠ K = 104°

Step-by-step explanation:

Note that KM = KL = 50mm ( congruent legs )

This indicates the triangle is isosceles with base angles congruent, both 38°

∠ K = 180° - (38 + 38)° = 180° - 76° = 104°

Answer:

So the answer is 398°

Answer:

The hypotenuse of a right triangle is 4m longer than the shorter leg and 2m longer than the longer leg. What are the lengths of the sides?

Just for variety, consider the hypotenuse = h, the short leg h-4 and the long leg h-2.

c^2 = a^2 + b^2; so h^2 = (h-4)^2 + (h-2)^2; h^2 = h^2 - 8h + 16 +h^2 -4h +4;

h^2 -12h +20 = 0 factors to (h - 10)(h - 2) = 0 so h = 2 or h = 10

Since (h - 2) = (2 - 2) = 0 and a triangle cannot have a side of zero length, 10 is the length of the hypotenuse.

h^2 = (h-4)^2 + (h-2); 10^2 = (10-4)^2 + (10-2); (10)^2 = (6)^2 + (8)

The hypotenuse is 10 cm, short leg 6 cm and long leg 8 cm.

B

Step-by-step explanation:

Answer:

It's not divisible

Step-by-step explanation:

18x²+11x+1

= 18x²+9x+2x+1

= (9x+1)(2x+1)

So, you see there's no terms (x+2) so it's not divisible

Although if you simplify it, it'll look like,

18x+51/(x+2)-25

So you can't remove the (x+2)

B:: 3^-5

Step-by-step explanation:

Symplifying, you should get 1/3 raised to the 5. flip the expression and you will get 3 to the negative 5. one to the 5 is just 1•1•1•1•1, which will result in 1, so we don't care about that.

here you go mate. sorry I just calculated straight away since you needed it urgently.

Answer:

I hope the image helps ^^

Step-by-step explanation:

First, i looked at the x + 10, so I chose a random point from ABC, (C) and moved it 10+.

Then I looked at y - 6, a moved it 6 units down.

There, I found C', so now that I had one of the points from A'B'C', I could make the other ones looking at the triangle ABC.

Since this is a translation, we're only moving the triangle to make ABC. So thats how I found the answer, does that make since?

x^2+y^2=100

Steps:-

We know Distance formula from origin

Now

[tex]\\ \sf\longmapsto \sqrt{x^2+y^2}=10[/tex]

[tex]\\ \sf\longmapsto x^2+y^2=10^2[/tex]

[tex]\\ \sf\longmapsto x^2+y^2=100[/tex]

The equation of the circle with radius r = 10 is given by x² + y² = 100

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the equation of circle be represented as A

Now , the value of A is

Let the radius of the circle be r

where radius r = 10

And , standard form of a circle is

( x - h )² + ( y - k )² = r²,

The center of the circle is the origin O ( 0 , 0 )

So , h = 0 and k = 0

On simplifying , we get

x² + y² = ( 10 )²

x² + y² = 100   be equation (1)

Therefore , the value of A is x² + y² = 100

Hence , the equation of circle is x² + y² = 100
