Answer:

  KM = 20

Step-by-step explanation:

If V is the midpoint of KM, then ...

  KV = VM

  2.5z = 5z -10

  0 = 2.5z -10 . . . . . . subtract 2.5z

  0 = z - 4 . . . . . . . . . divide by 2.5

  4 = z . . . . . . . . . . . . add 4

We know that V bisects KM, so KV is half the overall length. That is ...

  KM = 2·KV = 2·2.5z = 5z

Using the value of z we found, ...

  KM = 5·4 = 20

34=9r-11 <br> help plzzzzzzzzzzzzz hurry
natali 33 [55]

Answer:

5

Step-by-step explanation:

Swap sides so that all variable terms are on the left hand side.

9r−11=34

Add 11 to both sides.

9r=34+11

Add 34 and 11 to get 45.

9r=45

Divide both sides by 9.

r= 45/9

Divide 45 by 9 to get 5.

r=5

Which lines can you conclude are parallel given that m∠7 + m∠11 = 180? Justify your conclusion with a theorem.
Ratling [72]

Answer:

Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.

Step-by-step explanation:

find out the statement that conclude are parallel given that m∠7 + m∠11 = 180

angle 7 and 11 are the consecutive interior angles . that is same side interior angles.

angle 7 and 11 are the consecutive interior angles and they are supplementary when the lines are parallel.

Line a is parallel to line b by the Converse of the Same-Side Interior Angles Theorem.

90 degrees + 5x + x needs to equal 180 degrees cant figure out the variables though
shepuryov [24]
X=15
90 + 5(15) + 15 = 180
90 + 75 + 15 = 180 
180 = 180

To get 15, I added up the the x's (which was 6 total), and divided 90 by them.

90/6 = 15

Then you just fill them into the equation.

Have a superb day!
