Which step in the construction of copying a line segment ensures that the new line segment has the same length as the original line segment

The second step ensures that the new line segment has the same length as the original segment.

Step-by-step explanation:

The steps to copy a line segment:

1. Move the compass center to point P.

2. Adjust the radius of the compass to the length of the original line segment (PQ).

3. Move the compass center to R.

4. Draw an arc that intersects the line to the right of R.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
