Which step in the construction of copying a line segment ensures that the new line segment has
Nesterboy [21]

The steps 5 and 6 in the construction of a new line segment  ensures the lengths are equal.

A line segment in geometry has two different points on it that define its boundaries. Alternatively, we may define a line segment as a section of a line that joins two points.

Below are the steps for copying a line segment:

  • 1. Let's begin with a line segment we need to copy, AB.
  • 2. we take a point C at this stage. That will be one endpoint of the new line section, either below or above AB.
  • 3. Now we place the the compass pointer on the point A of line segment  AB.
  • 4. We spread the compass out until point B, making sure that its breadth corresponds to the length of AB.
  • 5. We place the compass tip on the point C created in step 2 without adjusting the compass's width.
  • 6. We now draw a rough arc without adjusting the compass's settings. we add a point D oh the arc . The new line segment will be formed by this.
  • 7. From C, draw a line to D;CD thus formed is equal to AB.

Hence steps 5 and 6 are the steps in the construction of a new line segment which ensures the lengths are equal.

The straight line with equation y=3/4x makes an acute angle theta with the x-axis.
yanalaym [24]
The angle is arctan(3/4) => sin(2t) = sin(2arctan(3/4)) =
2sin(arctan(3/4))cos(arctan(3/4)) 

Let z = arctan(3/4) => tan(z) = 3/4 

2sin(arctan(3/4))cos(arctan(3/4)) = 2sin(z)cos(z) = 2(3/5)(4/5) = 24/25 

<span>cos(2t) = cos^2(t) - sin^2(t) = cos^2(z) - sin^2(z) = (4/5)^2 - (3/5)^2 = (16 - 9)/25

= 7/25

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Write a division number story with an answer of 3/5
katrin [286]

Peter has 4 friends. He invited them to his home. He ordered a pizza of his favorite and made it into 5 slices.

Few minutes later, one of his friends Smith came and they enjoyed one slice of pizza each.

Now, the question is what portion of the pizza left for his remaining friends?

Answer :

Peter made the pizza into 5 pieces.

So, 1=\frac{5}{5}

Peter and Smith had \frac{1}{5}th of the pizza each.

So, the remaining portion = \frac{5}{5} -(\frac{1}{5}+\frac{1}{5})

=\frac{5}{5} -\frac{2}{5}

=\frac{3}{5}
