Answer:

the length is 10

Step-by-step explanation:

√(1 - 9)2 + (12 - 18)2 =

√(-8)2 + (-6)2 = √64 + 36 =

√100= 10

Answer:

Length of AB = 10

Step-by-step explanation:

This can be found by using the distance formula.

Distance Formula = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) is the first coordinate pair and (x_2,y_2) is the second coordinate pair

<em>Thus</em>

<em>x_1 = 9 and y_1 = 18</em>

<em>x_2 = 1 and y_2 = 12</em>

<em>Plugging them into the formula, we get:</em>

<em>Length = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(12-18)^2+(1-9)^2}. WHich is equal to 10.</em>

<em>Length is 10</em>

ohaa [14]

Answer:

See the proof.

Step-by-step explanation:

<u>Statement     </u><u>                                                         </u><u>   Reason</u>

1.∠1 and ∠2 are supplementary angles     ---           Given  

2. m∠1 + m∠2 = 180°     ---                  Linear pair, they are supplementary                                

3. m∠1  and m∠3 are supplementary angles --  m∠1 + m∠3= 180

                                                                              (Supplementary angles add upto 180 degrees)  

4.  m∠1 and m∠3           ------                                 Exterior sides in opposite rays

5.   m∠1 + m∠2 = m∠1 + m∠3  ------                       Transitive property  

6.    m∠2 = m∠3                     --------------                Subtraction  property

7.   l || m  ------------- If two lines are cut by transversal the alternative interior

                               angles are the same, then the lines are paralle.

Thank you.

N^2+100=20n<br><br> Please show work
adell [148]
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
