_________ are defined as lines that never have one point in common.
barxatty [35]

Answer:

The correct option is option number 4. Parallel lines are defined as lines that never have one point in common.

Step-by-step explanation:

Parallel lines: Parallel lines are the lines that will never cross each other. As they never meet, so they won't have a common point.

On the other hand, the other options are incorrect. This is because,

Perpendicular lines: Perpendicular lines are the lines that make 90 degrees angle with each other.

Skew lines: Skew lines are the lines that are not present on the same plane.

Coplanar lines: Any lines which are known to occur on the same plane are termed as coplanar lines.

Can somebody anybody please help me with this math problem?
Annette [7]

Answer:

30°

Step-by-step explanation:

Angle C = 55°, Angle D = Angle A = 65°, Angle B = 2x

Sum of angles in a triangle = 180°

65° + 55° + 2x = 180

120 + 2x = 180

2x = 180 - 120

2x = 60

x = 30°

A student earned a grade of 80% on a math test that had20 problems. How many problems on this test did the student answer correc
Georgia [21]

Answer:

Only 16 problems correct

Step-by-step explanation:

Well I thought that since 80% is  4/5 then I should do 20 divided by 5 which will get me 4 and since I'm doing 4/5 I should go all the way up to 80% of 20 which will get me 16.

I'm not making that much sense but

Hope this helps :)

Find the variable 15 = 5 − 13
Lyrx [107]

Answer:

0.4

15 = 5p - 13

-13 = 5p -13

----------------  ( subtract 13 on both sides )

 <u> 2 = 5p</u>

  5 = 5p

----------------  ( divide 2 by 5 )

  p = 0.4

( p equals 0.4 )
