Which of the following steps is included in the construction of a perpendicular line through a point on a line?
Molodets [167]

Answer:

Connect arcs that are above the original line with a straightedge ⇒ 2nd

Step-by-step explanation:

* <em>Lets revise how to construct a perpendicular line through a point</em>

<em>  on the line</em>

- <u>Given:</u> line AB and point P lies on it

1. Place your compass pin at P and draw an arc of any size below  

  AB that crosses the line twice at points C and D  

2. Stretch the compass to a larger distance

3. Place the compass pin on point C and draw a small arc above 

   the line  

4. Without changing the distance of the compass place the  

   compass pin on point D and draw another small arc intersects

   the small arc  from C at point E

5. <u>Using a straightedge, to join P which is on the original line and E </u>

    <u>which is the intersection point of the two small arcs above the </u>

    <u>original line,</u> then PE is perpendicular to AB  at E

- From the steps up the step is including in the construction of a

 perpendicular line through a point on a line is:

 <u><em>Connect arcs that are above the original line with a straightedge</em></u>

* <em>Remember:</em>

- The step of Connect arcs that are above and below the given line

  with a straightedge is in the construction a perpendicular from a

  point off the line

- The step of Create arcs on either side of a point that is off the

  given line is in the construction of a perpendicular bisector

  of a line

- The step of Create a copied angle by using the first two lines as the

  original angle in the construction of the parallel lines

- Look to the attached figure to help you

jarptica [38.1K]

Answer:

7x (x + 1 ) ( x + 3 )

Step-by-step explanation:

7x³ +28x² +21x

7x ( x² + 4x + 3 )

7x [ x² + 1x + 3x + 3 ]

7x [ x ( x + 1 ) + 3 ( x + 1 ) ]

7x (x + 1 ) ( x + 3 )

The pentagonal prism has a perpendicular distance of 14 units between the bases. The volume of the prism is 840 cubic units. Wha
nadezda [96]
<span>Prism Volume = Area of Base • Height
</span>
Area of Base = Prism Volume / Height
Area of Base = 840 / 14
Area of Base = 60
pentagon area = 5 * side^2 / 4 * tan (180 / 5)
side^2 = [pentagon area * 4 * tan (180 / 5)] / 5
side^2 = [60 * 4 * tan (36)] / 5

side^2 =240 * 0.72654 / 5

side^2 = <span> <span> <span> 174.3696 </span> </span> </span> / 5
